The primary bottleneck to this growth is the availability of electricity.
The bottleneck for building some AI datacentres and switching them on is electricity, sure, but that's not what drives growth. There also needs to be demand for the additional capacity; people need to be waiting for capacity to catch up so they can do the useful work that grows [society|GDP|something] that they aren't doing right now.
There's also very likely to be diminishing returns from additional capacity if we're near or over the limit of productive use. And there's the opportunity cost of what could have been done with that [money|land|electricity].
This is a much more complicated system than "people say they need more AI -> build datacenter -> power datacenter -> magical growth!"
In the Innovation Adoption Curve, we are absolutely beyond the Early Adopters phase and possibly the Early Majority. The growth rates necessarily have to start trending down because there’s no one left to sell to.
TFA isn’t about consumer usage, it is about training the next generation models. An interesting thought I heard recently is that a SOTA model has about the same parameters as the number of synapses in a Golden Retriever’s brain that are not dedicated to biological processes like breathing. Most of that should be wrapped in double quotes, don’t take it literally! But that number is about 100x lower than the same synapses in a human brain.
If the next order of magnitude costs 40B, I wonder if it’s even possible to get to the one after.
Cheap ubiquitous distributed power systems will change the world in many weird ways. Watch small modular nuclear offer home installation for ~$reasonable and getting cheaper every year.
Fast forward 20 years from the advent of essentially infinite energy results in WWIII and a new “Great Detente” but only after all the assholes have wreaked all the havoc they can.
There are dark days ahead but ultimately a brighter future. Sucks to live through that transition phase though.
I'd like to see a well reasoned plan to install small modular nuclear power at peoples houses that prevents the mentally ill, criminally reckless or terrorist minded people from cracking them open and obtaining access to the isotopes.
have you never visited a rural neighborhood? or an affluent neighborhood?
there are still many neighborhoods where people leave their doors unlocked because it is actually that safe. not every location is rife with criminal activity, and many are well protected.
Serious question, do you actually think that if you distribute millions of small nuclear reactors to homeowners geographically spread out around all of North America, 0.000% of them will be dangerously mentally ill, criminally reckless or inclined to terrorist like activity? Based on the frequency and number of mass shooter type incidents, (or like, David Koresh and the Branch Davidians) this would be a very naive view.
Question for the experts: does the power crunch mean that AI hyperscalers will turn off previous generation GPU datacenters to free up power for their new Vera Rubin GPUs?
You don’t even need to mention the long-term sustainability benefits of renewable energy. It is simply the dominant option economically. Dollars in, watts produced, fossil energy can’t touch it.
Politics is merely a downstream effect of the root of the problem: corruption and regulatory capture. Regression into the authoritarian petrostate pattern.
Who is opposing renewable energy? Texas is projected to top California as the state with the largest amount of solar before the end of the Trump administration.
This is part of why the AI bubble will burst. The only way to make the profit numbers backing the loans to AI companies is to get increased capacity, and the capacity requires energy, and the energy won't arrive in time, only partly due to all the factors here, and partly because building transmission and generation is speculative and can fail for a number of reasons.
US administration can try to pull a China and basically remove all regulatory barriers (following existing playbook of "do whatever we want and wait a year or two for the courts to catch up and stop us"). It'll create havoc that will make people very upset (more so than the people that already protest DCs in their backyards). But even then, it's construction on varied terrain and property over long distances; you can't predict exactly how that will go. Triple the estimated timeline and that is probably doable, but current AI investment likely can't wait that long, unless somebody can pull additional hundreds of billions out of a hat to extend lines of credit or a ponzi-scheme-esque paying-creditors-with-newly-lent-money. In that time the market will realize the hype was hype, the gains were modest, they'll start divesting, and then the house comes down.
One way around that might be to deploy thousands more gas turbines and make rural air quality look like 2010 Beijing. It will probably happen if things get really tight, and we'll see how the current administrations's base responds; if they stick it out, the market gets a reprieve.
We should have been building more nuclear. We’re not going to upgrade civilization with windmills and putting on sweaters. Think of how much power we’ll need for millions of robots?

There isn’t much need to extract isotopes if you have an actual working reactor, is there? Just use that as-is to cause whatever damage.

I think it’s more likely we’ll raise prices until demand lowers enough to match supply.
Open models enforce a floor on prices, unless overall compute is so constrained that those prices rise also.
Maybe it's the same thing I heard it was six months ago when it was determined that more hardware was sold than twice the nation's supply of electric.
Crusoe bypasses the grid completely by leveraging old batteries and wasted resources to power compute.
‘the abundance of [AI] will be limited by the abundance of energy’.
And the reason current US policy opposes clean, renewable energy is --- purely political.

The current US admin:

but they are slowly being beaten back:

What isn't "purely political?"
Everything is political in the world, unfortunately.

I don't see how expensive energy helps us "upgrade civilization".
Unlimited energy for 200 years is a good step, no?
Its only expensive because its been regulated to death. In terms of potential energy output in a given area its tops.
