That is a good correlation when you think about how much more energy-efficient transistors are than vacuum tubes.
Vacuum tube computers were a thing for a while, but it was more out of desperation than systematic intellectual progress.
OTOH you could look at the present accomplishments like it was throwing more vacuum tubes at a problem that can not be adequately addressed that way.
What turned out to be a solid-state solution was a completely different approach from the ground up.
To the extent a more power-saving technique using the same hardware is only a matter of different software approaches, that would be something that realistically could have been accomplished before so much energy was expended.
Even though I've always thought application-specific circuits would be what really helps ML and AI a lot, and that would end up not being the exact same hardware at all.
If power is truly being wasted enough to start rearing its ugly head, somebody should be able to figure out how to fix it before it gets out-of-hand.
Ironically enough with my experience using vacuum tubes, I've felt that there were some serious losses in technology when the research momentum involved was so rapidly abandoned in favor of "solid-state everything" at any cost.
Maybe it is a good idea to abandon the energy-intensive approaches, as soon as anything completely different that's the least bit promising can barely be seen by a gifted visionary to have a glimmer of potential.
