To your first question, nop, I have no idea how much energy takes to index the web in a traditional way (e.g MapReduce). But I think, in recent years, it’s been pretty clear that training AI consumes more energy (so much that big corpo are investing in nuclear energy, I think there was an article about companies giving up meeting 2030 [or 2050?] carbon emission goals, couldn’t find it)
About the second… I agree with you, but I also think that the problem is much bigger and complex than that.
Can you split a uranium-235 atom in your head?
