I'm mostly talking about incredibly environmentally destructive data centers and energy use on the current trajectory. Not even thinking about water problems, the gas and coal requirements alone are climate disasters. [1] [2]

But if it is a bubble, which many would argue is the case, an AI capex bust with it's circular financing collapse is one of, if not THE top threat to global financial stability. ~$725B combined hyperscaler capex in 2026 against roughly $25B of AI service revenue in 2025 on $250B+ of infrastructure spend. Not exactly a promising situation. [3] [4]

This is immediate-picture, I'm not talking about a singularity extinction event. Just what's actually happening right now and the trajectory of the next 4 years.

Hmm. I'm as big an environmentalist as anyone, but I'm pretty sceptical of the data centers as eco disasters narrative. Your sources indicate that renewables already meet over 50% of new data center demand, and the demand is predicted to drive advancements in technologies like SMRs. The water use of a data center is less than a golf course. Gas and coal cannot compete with renewables on price and speed of deployment, and increased utilization of the existing grid can help cover fixed costs which dominate the cost structure, resulting in decreased prices overall even as we increase deployment of renewables.
China managed to double energy production between 2015-2025 (including 60 nuclear reactors). On paper the west should be able to do the same, tech companies are putting huge money into solar, natural gas, and nuclear. Most of the limitations are as you mention people protesting the whole idea of new industry and energy, which is the source of most of the risk. That plus open model/Chinese competition undercutting some big US IPOs.

The long term investments in datacenters and chip manufacturing will likely coincide with with growth in demand from humanoid robots and self-driving cars, so it is likely going to happen anyway over the next decade.

It just will take longer than people expect which creates financial risk, but US capital markets are more resilient than people think.

> people protesting the whole idea of new industry and energy,

I may be venturing into aluminum hat territory but it appears that oil and gas companies and conservative organizations are pumping all sorts of FUD and misinformation into the anti-solar, anti-battery movement, period.

One of the arguments against widespread solar is that it's environmentally damaging, yet, time and time again, it's shown that solar farms increase soil moisture, improve biodiversity in plants and insects, period. If cattle or sheep are grazing on that land, the shade reduces their stress from summer heat and can also shelter them sometimes in the winter.

Again, may be complete BS, but apparently Chinese desert solar farms are increasing the moisture in the desert, making it easier for plants to grow and increasing rainfall downstream from the plant solar farms.

China has tightly integrated domestic supply and a centrally planned economy. That's why China has consistently been able to do things that are simply impossible in the west.
The facts don't support a real eco panic. IMO it's a proxy for middle class job security fears, displacing into known middle class shibboleths. It can be sincere, but it's motivated reasoning.
