I wrote this in the comment section of the video:
"You claim that AI development will slow because we will run out of data, but synthetic data is already being used to train AIs and it actually works! AlphaGo was able to go from knowing nothing about the most complicated board game in the world called "GO" to being able to play it at a superhuman level in just a few hours by using synthetic data, it played games against itself. As for power, during the last decade the total power generation of the US has remained flat, but during that same decade the power generation of China has not, in just that same decade China constructed enough new power stations to equal power generated by the entire US. So a radical increase in electrical generation capacity is possible, the only thing that's lacking is the will to do so. When it becomes obvious to everybody that the first country to develop a super intelligent computer will have the capability to rule the world there will be a will to build those power generating facilities as fast as humanly possible. Perhaps they will use natural gas, perhaps they will use nuclear fission."
