The first article of this series argued that in principle we should expect our personal identities to survive a transition to artificial brains. Obviously there remains the minor technical problem of how to actually build such brains. The most popular conception of how to approach this is known as ‘whole brain emulation’, which entails replicating the precise functional architecture of our current brains with synthetic components.
This is a cautious approach, in that the closer the design of your new brain to your old one, the more confident you can be that every precious memory and personality trait has been copied over. However, this also means copying over all the limitations and flaws that evolution bestowed upon our biological brains. Yes, you won’t have to worry about your cells ageing anymore – a definite upside! But you will remain stuck with outdated structures like the amygdala and hippocampus as well as the convoluted circuitry linking them together. It would be like upgrading your 1950s classic car engine with all new modern parts. It’s still the same, inefficient, loud, polluting machine, just shinier and more durable.
This is why we will choose to design far more advanced brains instead. Though this raises a risk of its own: what if we create kinds of minds that are far more powerful than our current ones and they destroy us before we have a chance to upgrade ourselves to rival them?
This is known as the ‘existential risk’ posed by artificial general intelligence (AGI). Read more »





Jeffrey Gibson. Chief Black Coyote, 2021.
Lucky you, reading this on a screen, in a warm and well-lit room, somewhere in the unparalleled comfort of the twenty-first century. But imagine instead that it’s 800 C.E., and you’re a monk at one of the great pre-modern monasteries — Clonard Abbey in Ireland, perhaps. There’s a silver lining: unlike most people, you can read. On the other hand, you’re looking at another long day in a bitterly cold scriptorium. Your cassock is a city of fleas. You’re reading this on parchment, which stinks because it’s a piece of crudely scraped animal skin, by the light of a candle, which stinks because it’s a fountain of burnt animal fat particles. And your morning mug of joe won’t appear at your elbow for a thousand years.
Harry Frankfurt died on July 16, 2023. As a philosophy student I came to appreciate him for his work on freedom and responsibility, but as a high school word nerd, I came to know him the way other shoppers did: as the author of one of those small books near the bookstore checkout line. That book, On Bullshit, had exactly the right title for impulse-buying, which has to explain how Frankfurt became a bestselling author in a field not known for bestsellers.
I had my first experience with Daylight Saving Time when I was 9 or 10 years old and living in Phoenix. Most of the country was on DST, but Arizona wasn’t. I knew DST as a mysterious thing that people in other places did with their clocks that made the times for television shows in Phoenix suddenly jump by one hour twice a year. In a way, that wasn’t a bad introduction to the concept. During DST, your body continues to follow its own time, as we in Phoenix followed ours. Your body follows solar time, and it can’t easily follow the clock when it suddenly jumps forward.

Unspeakable horrors transpired during the genocide of 1994. Family members shot family members, neighbours hacked neighbours down with machetes, women were raped, then killed, and their children forced to watch before being slaughtered in turn. An estimated 800,000 people were murdered in a country of (then) eight million. Barely thirty years have passed since the Rwandan genocide. Everywhere, there are monuments to the dead, but as an outsider I see no trace of its shadow among the living.
