Caveat. I did pencil in data centres using nuclear as highly probable some years ago (I worked in geophysical energy+mineral exploration for decades then moved to resource intelligence presentation).
Won't I don't see is the "inadvertently saves us from catastrophic climate change" part .. sure, that might happen but it doesn't follow that it will - the more probable outcome is that overall we humans just consume even more energy with some of that addditional energy coming from nuclear.
It's a tall ask for nuclear to cover projected additional demand (see: global energy consumption data over time), it's even more of an ask to expect it to make inroads on existing demand also.
The closest thing we have for examples of nuclear at scale is Korea in recent past decades and currently China right now: https://itif.org/publications/2024/06/17/how-innovative-is-c...
Nuclear is also expensive in comparison to alternatives (depending upon local expertise): Australia's costings (cold start on nuclear power tech) are that the better ROI over next four decades on energy investment now is not nuclear (2024 CSIRO energy report).
