"In the past few years, we have seen seemingly superhuman capabilities of AI systems"
Who's we and what is superhuman to you?
Meanwhile, Nvidia and Intel introduce even more power hungry hardware (ie. 3090 Ti) and specs (ie. ATX's 12v only) to find lower energy consumption routines. It's similar to using more cash bills to collect more coin change.
FWIW, I don't' think "AI" advancement should be determined by how much power it does or doesn't use, but how that system is designed. To me, current AI seems to mean work harder, not smarter.
