I'm glad to see leading voices in AI like @sama, @ylecun, and @ilyasut ponder the question of artificial consciousness. We research this @SentienceInst because it's one of the most important questions for the long-term future. I'd like to introduce the topic in a brief thread 1/n
First, the meaning of consciousness is deeply contested among philosophers and scientists. There are 3+ more precise terms:
- thought, typically a linguistic stream of words
- perception, either through the 5 senses or imagination
- sentience, positive and negative emotions 2/n
Even these are contested: Are they behaviors? Processes? Functions? Dualist/nonphysical)? Ineffable? Etc.
I take the eliminativist view that because our terms are so vague, consciousness doesn't exist objectively and we need specific measures instead: sentienceinstitute.org/blog/what-is-s… 3/n
What specific features would indicate sentience or consciousness in AI? Our researcher Ali Ladak wrote a blog post on the specific features that have been proposed. If AI should be called conscious, it will probably be one or more of these features: sentienceinstitute.org/blog/assessing… 4/n
Modern transformers like GPT-3 have few if any of these features. Again, I don't think there is an objective answer to this. Definitions of consciousness like "what it's like to be" something or an "inner listener" are much too vague to answer this. 5/n
Modern NNs might have "a modicum of consciousness, but probably less than an insect." That's about as precise as we can be with the disagreement, vagueness, and uncertainty.
But the more important question is how we should act regarding the future possibility of sentient AI! 6/n
There are good reasons to think the long-term future will be populated mostly by digital minds, not biological. @xuenay outlined these in 2012. AI can think faster, copy itself more easily, travel at light speed, self-modify, better cooperate, etc. philpapers.org/archive/SOTAOA… 7/n
Humans hunt the largest animals and drive them to extinction. We have always done so. The first homo sapiens lived with some amazing larger-than-life megafauna that may still be alive today if we weren’t such a murderous species. An appreciation thread for these real-life titans:
Megatherium: 6m (20ft) giant sloth weighing up to 4 tons. Like modern sloths, they slowly lumbered through the jungle. They could probably walk on two legs. Fossils have cut marks, indicating overlap with early humans. Extinct around 8,500 BC (first homo sapiens ~300,000 BC).
Glyptodon: 1.5m (5ft) armadillo. This bad boy was around the size of a Volkswagen Beetle. While herbivorous, their heavy armor and bony tail helped in fights with conspecifics and defense against predators. Extinction around 10,000 BC at the end of the Pleistocene Epoch.
Most people have seen the scary math on how unprepared humanity is for #COVID2019, particularly US medical infrastructure (e.g. masks, hospital beds, HT @LizSpecht). But I don’t think most people realize that this crisis, and S&P 500 drop, was entirely foreseeable. A thread. 1/11
The first layer of the onion is that we knew a global pandemic was coming. For just one example, in a 2015 discussion with @EzraKlein, @BillGates said a deadly flu-like pandemic is the most predictable disaster in the history of the human race (vox.com/2015/5/27/8660…). 2/11
This perfect storm has been obvious for years: wild animal trade and factory farms to transfer diseases to humans—often with antibiotic resistance, dense urbanization and low sanitation to incubate an outbreak, mass travel to spread it, and a lack of government preparation. 3/11
