I am optimistic. I will get downvoted to oblivion, but I want to share what I honestly observe:
1. AI demand is driving huge investment in production of carbon-free energy at scale.
Yes, AI is sucking up all the immediate term cheap fossil-fuel energy while it can. But it needs more, so it's driving carbon-free investment.
Immediate term with Small Modular fission Reactors (SMRs)
... and immediate term, multiple commercial fusion energy plants are being built.
2. Commercially viable carbon-free energy at scale is coming online in < 10 years
SMR is real, exists today, and just needs economies of scale ... and stable regulation. AI datacenters are driving the orders now and even if MAGA cultists keep USA out a few more years, science-accepting countries will be investing in clusters of those, rather than coal plants, when they see working examples and so less risk.
The Fusion plants this decade will not be just prototypes, but plants that produce more energy as a whole than they take in, multiple times over, and ofc don't produce nuclear waste. This is largely made possible by high temperature superconductors (which didn't exist commercially when ITER was built) and a demo plant fully online in 2027
EDIT: ofc we should reduce excess CO2 emissions immediate term, don't misconstrue long term optimism for polyannish denial of imemdiate term emergency
Well, maybe you aren't aware of how it's being used to design proteins to create therapies for pretty much... everything, from cancer to Crohn's. Another 2-3 years before you see products in human trials.
Or how it's revolutionized climate science and weather forecasting.
If all you see is the hype Grok images and SEO slop, it's reasonable to reject the technology. But that would be deeply misguided.
