What is the difference between hybrid and heirloom? Are hybrids bad? Are they natural? What is an heirloom? How old is an heirloom? Those questions and more are answered in this episode of Levi Explains.
Interview with Scott Aaronson — covering whether quantum computers could have subjective experience, whether information is physical and what might be important for consciousness — he touches on classic philosophical conundrums and the observation that while people want to be thorough-going materialists, unlike traditional computers brain-states are not obviously copyable. Aaronson wrote about this his paper ‘The Ghost in the Quantum Turing Machine’ (found here https://arxiv.org/abs/1306.0159). Scott also critiques Tononi’s integrated information theory (IIT).
Scott discusses whether quantum computers could have subjective experience, whether information is physical and what might be important for consciousness — he touches on classic philosophical conundrums and the observation that while people want to be thorough-going materialists, unlike traditional computers brain-states are not obviously copyable. Aaronson wrote about this his paper ‘The Ghost in the Quantum Turing Machine’ (found here https://arxiv.org/abs/1306.0159). Scott also critiques Tononi’s integrated information theory (IIT).
Questions include: - In “Could a Quantum Computer Have Subjective Experience?” you speculate that a process has to ‘fully participate in the arrow of time’ to be conscious, and this points to decoherence. If pressed, how might you try to formalize this?
- In “Is ‘information is physical’ contentful?” you note that if a system crosses the Schwarzschild bound it collapses into a black hole. Do you think this could be used to put an upper bound on the ‘amount’ of consciousness in any given physical system?
- One of your core objections to IIT is that it produces blatantly counter-intuitive results. But to what degree should we expect intuition to be a guide for phenomenological experience in evolutionarily novel contexts? I.e., Eric Schwitzgebel notes “Common sense is incoherent in matters of metaphysics. There’s no way to develop an ambitious, broad-ranging, self- consistent metaphysical system without doing serious violence to common sense somewhere. It’s just impossible. Since common sense is an inconsistent system, you can’t respect it all. Every metaphysician will have to violate it somewhere.”
Many thanks to Mike Johnson for providing these questions!

Blockchain shows major potential to drive positive change across a wide range of industries. Like any disruptive technology, there are ethical considerations that must be identified, discussed, and mitigated as we adopt and apply this technology, so that we can maximize the positive benefits, and minimize the negative side effects.
Own Your Data
For decades we have sought the ability for data subjects to own and control their data. Sadly, with massive proliferation of centralized database silos and the sensitive personal information they contain, we have fallen far short of data subjects having access to, let alone owning or controlling their data. Blockchain has the potential to enable data subjects to access their data, review and amend it, see reports of who else has accessed it, give consent or opt-in / opt-out of data sharing, and even request they be forgotten and their information be deleted.
Monetize Your Data
Blockchain enables cryptocurrency. Think of blockchain as a platform, and a cryptocurrency as a particular application that can run on blockchain, along with many other applications such as those that can enable data subjects to control their data. Users can be rewarded with cryptocurrencies for opting into, or giving consent to collaborate and share their data. For example, a patient may opt into participation in a clinical trial, and in so doing make their data available for research within that clinical trial. This capability has the potential to provide a direct value feedback loop whereby data subjects can monetize their data. This is a huge leap forward from today where data subjects give up their data free, in many cases unaware, and organizations collecting it make highly profitable businesses out of monetizing data with nary a cent going back to the data subject. However, in enabling data subjects to own, control, and monetize their data guardrails must be put in place around this to ensure that data subjects are fully informed of not just monetization opportunities, but also how their data will be used, any risks, and their rights.
Disintermediation and Disruption
Historically collaboration across a group of organizations has required a central trusted intermediary in a “hub and spoke” architecture where the intermediary is at the center and mediates all interactions across the network. One can see examples of this across many industries. In financial services we have banks and banking networks. In healthcare we have clearinghouses and health information exchanges. In most industries we have supply chains where distributors are the hub connecting manufacturers and suppliers with dispensaries and retailers. Unfortunately, many intermediaries have abused their role and introduced excessive costs, delays, and single points of failure where if they are unavailable collaboration across the whole network is halted. To be clear, where physical goods flow, such as in supply chains, centralized hub and spoke architectures will endure. However, when it comes to the flow of digital goods, including any information, cryptocurrencies, crypto-tokens, or otherwise, blockchain has the potential to enable decentralized collaboration across a consortium of organizations in near real-time, and without the added cost, and delay of the intermediary. Since blockchain is decentralized, it eliminates the central single point of failure that makes hub and spoke architectures vulnerable to attacks on the availability of data or systems such as ransomware or DDoS (Distributed Denial of Service). However, with this disintermediation and disruption the common assertion is that many will lose their jobs. Actually, with blockchain there is a different role for an intermediary around training, system integration, support, governance, consensus building across the consortium, and so forth, so there is an opportunity for intermediaries of today to evolve, adapt to blockchain, and even leverage blockchain to their benefit.
Hyper-Efficiency and Job Loss
Today many common types data are maintained redundantly across silos. Think of the last time you changed your phone number or address and had to visit hundreds of websites to update it. Did you visit them all? Probably not (who has time), and so many of the copies of your data are old, inaccurate, etc. This system results in massive collective cost and causes major inefficiencies. Rather than maintain common data in one place, and update it once as needed, and share it near real-time across the consortium of organizations that need it, the cost to maintain common data is multiplied by the number of organizations that have copies and maintain it independently. Further, inconsistencies in this data cause friction and additional cost in the system, and frustration. If your address is not updated mail goes to the wrong place, needs to be forwarded, or maybe you didn’t do forwarding and so you lose it and absorb whatever the impact. In healthcare if records are inconsistent across payers and providers, medical claims can bounce causing delays in payment and so forth. So blockchain having the potential to help solve this sounds good, right? Well, what about the millions of people whose job it is today to maintain redundant copies of information across these organizations and silos. In using blockchain to pave the way for secure, and hyper-efficient maintenance of common, shared data, we may inadvertently disrupt the jobs of millions of people doing mundane, redundant data maintenance today. This is not to say we should not move forward with blockchain and realize its benefits, but we should do so fully aware of the impacts and help those impacted proactively adjust, retrain and move onto more useful, interesting, and higher paying roles.
Environmental Impacts
Public blockchains such as bitcoin span untrusted networks, with untrusted participants, and so must use conservative consensus algorithms such as PoW (Proof of Work) which require mining. To be competitive in mining one must invest in massive amounts of hardware that use massive amounts of electric power. This is a considerable environmental and ethical concern. For public blockchains to be feasible going forward we must find new ways of enabling blockchain consensus in ways that do not require massive amounts of hardware or electric power. Key clarification: this challenge is associated with mining and public blockchains and the consensus algorithms they use, whereas private / consortium blockchains, which represent the vast majority of blockchains used in industries such as healthcare, don’t typically have mining, but rather validation of transactions and blocks which does not require any significant additional hardware or electricity. Therefore, while this is a challenge for public blockchain applications such as bitcoin, it is not an issue for private / consortium blockchains.
Anonymity, Cryptocurrencies, and Crime
Ransomware is enabled by anonymous payment methods such as bitcoin. An attacker can infect your system, encrypt your data, and demand payment in bitcoin, and you can pay them with nary an idea of who attacked you, nor the ability for you or law enforcement to identify them. While cryptocurrencies and crypto-tokens have incredible potential for good, they are in this respect a double edged sword since they also pave the way not only for ransomware attacks, but DDoS, any many other types of crime. On the other hand, blockchain has incredible potential to help mitigate many types of fraud related crime so blockchain and crime is a multi-faceted ethical consideration. For more on this see Blockchain as a tool for anti-fraud.

Prince Philip’s driving days don’t appear to be numbered just yet after a replacement Land Rover was delivered to him today — less than 24 hours after his horror smash.
The black Freelander — an exact replica of the one Philip wrote-off yesterday — was driven off the back of a lorry and into Sandringham at around Midday.
The Duke of Edinburgh, 97, who had to be pulled from the wreckage, told police he had been ‘dazzled by the sun’ before the collision near the Norfolk estate at 2.45pm yesterday.
80 Acres Farms, an Ohio-based vertical farming startup, has raised private equity funding from Virgo Investment Group, a private equity firm from San Francisco for the construction of what it says will be the first fully automated indoor farm.
AgFudnerNews can reveal that the deal was worth more than $40 million in equity capital, according to sources close to the deal.
The funding will go towards the completion of 80 Acres’ Hamilton, Ohio facility, which was announced last year and is set to be partially operational in the next few months.
Here’s a new photo that shows Earth and the Moon from a whopping 71 million miles away. It was captured by NASA’s OSIRIS-REx, which is currently on a mission to obtain a sample from a near-Earth asteroid and return it to Earth.
The photo was captured on December 19th, 2018, using the spacecraft’s NavCam 1 camera. Earth and the moon can be seen on the bottom-left side of the photo. The much larger white object in the upper-right side is asteroid Bennu.
Earth is 71 million miles (114M km) away in the photo, while Bennu is just 27 miles (43 km).
A recent study, affiliated with South Korea’s Ulsan National Institute of Science and Technology (UNIST) has introduced a novel targeted drug delivery system in the fight against cancer.
A new report reveals 42% of global coal capacity is currently unprofitable, and the United States could save $78 billion by closing coal-fired power plants in line with the Paris Climate Accord’s climate goals. This industry-disrupting trend comes down to dollars and cents, as the cost of renewable energy dips below fossil fuel generation.
Across the U.S., renewable energy is beating coal on cost: The price to build new wind and solar has fallen below the cost of running existing coal-fired power plants in Red and Blue states. For example, Colorado’s Xcel will retire 660 megawatts (MW) of coal capacity ahead of schedule in favor of renewable sources and battery storage, and reduce costs in the process. Midwestern utility MidAmerican will be the first utility to reach 100% renewable energy by 2020 without increasing customer rates, and Indiana’s NIPSCO will replace 1.8 gigawatts (GW) of coal with wind and solar.
Lazard’s annual Levelized Cost of Energy (LCOE) analysis reports solar photovoltaic (PV) and wind costs have dropped an extraordinary 88% and 69% since 2009, respectively. Meanwhile, coal and nuclear costs have increased by 9% and 23%, respectively. Even without accounting for current subsidies, renewable energy costs can be considerably lower than the marginal cost of conventional energy technologies.
