Sure there is.

1. The cost of each new generation of training runs appears to be rapidly rising

2. The Trump admin just told the leading model to stop making it available to non-Americans, which in practice meant stop providing it at all

3. The factories to make the hardware are hitting bottlenecks, and while they've currently been navigated around, there's never a guarantee the next one will be

Currently I'm wondering at what point the direct impact on the US energy supply gives the US a taste of Baumol's cost disease as AI companies continue to outbid everyone else for electricity.

There are some counters to this, especially in electricity. We'll see massive expansions of wind and solar in the US because of this. Both the speed of install and low costs will guarantee it.

Implausible while Trump remains in office. He hates renewables, shuts them down even when doing so actively costs money.

Between AI hallucinated content and the politicisation of the numbers, I'm not sure how much AI compute capacity is being planned right now; would you accept a claim of 300 GW? It's a number I heard recently.

Given the capacity factor of PV, even China would have to think carefully before supplying that much PV over the next few years (300 GW avg ~= 3TW nameplate).

(Not sure about wind, wind's CF seems to vary between years).

Unless it's something on federal land businesses are pretty much ignoring Trump on renewables.

And 300GW power planned doesn't seem too far out of bounds, there are a huge number of 'planned' data centers all over the US.

World wide over 800GW of solar and wind was installed in 2025 and 2026 numbers should be over 1TW of renewables. How much of that will the US install itself is a much smaller percent, but as power prices increase the pace to profit off of it will quicken. I know China installed over 300GW themselves last year.

Except for all of the tariffs etc.

And that's without Trump seeming to be actively choosing winners based on favour to him, as with supporting Grok despite the data centre pollution in another thread and *possibly* (I don't wish to overstate my case) the ban on Fable.

This is why I wrote:

When the recent good news is that "the world installs 800 GW of PV" (TBH, I thought this was closer to the last 12 months of just PV than the sum PV+wind), that's the nameplate capacity, not the actual year-long-average output, which is about a tenth of that.

The most recent PV capacity factor number on Wikipedia was 13%, which would make "800 GW" only 104 GW in real output; the figures I see for wind are that the CF is 25% (with much higher variability) but the nameplate capacity is lower, so they're pretty close as totals in real total currently installed output.

As long as Chinese companies keep pushing on, so must US companies too.

It would not surprise me at all if we suddenly start seeing top US AI companies lobby against Chinese models, or even the gov. making it illegal to use Chinese AI models.

But in this day and age, I just don't think it is possible. A distant third option would be that the big AI companies try to make hardware so expensive that people simply can't run their own models, while blocking access to foreign models.
