Subjective.
> Nobody in AI likes paying big power bills.
Nobody anywhere "likes" big power bills, including in crypto. That said for crypto, this actually had the effect of driving everyone to the lowest priced power sources on the planet (many of which ended up being 'green' energy) and building more efficient systems.
The fact of the matter is that AI is so hot right now that people are paying absurd rates for power and nobody is talking about the usage. Like I said above, datacenter demand is off the charts right now. They are announcing space on a Friday and it is gone by Monday.
> This is the general pattern in computing, except for crypto. We start with room sized monsters like ENIAC and improve and improve until something better fits in a solar powered watch.
"except for crypto" is wrong.
ETH started as an ENIAC and now it is a solar powered watch. In fact, ETH pegged itself to GPUs from the start, which meant that it didn't have the same sort of hardware competition that Bitcoin has. ETH's PoW algo is memory hard and limited by the onboard controller bandwidth, which meant that the fastest GPUs were not always the more ROI efficient... you didn't need to continuously upgrade the hardware to latest greatest.
