The serious answer?
Well, the first thing that will happen is that the bubble will burst, and the US economy - propped up by AI stocks as it is - will tank. Whether it takes everyone else down with it is anyone's guess; however, we're relatively insulated from the direct economic effects here in the UK because power is too damn expensive for anybody to cost-effectively host an AI datacentre here. Banks will definitely have a bad day, though, as will all the index-linked funds (and therefore pensions) that were forced to buy SpaceX-AI stocks.
That means that either OpenAI, Anthropic etc will go bust (SpaceX will suddenly find a way to spin the AI business off into its own short-lived side hustle, having made and lost a bunch of cash in the IPO based on it), or their prices will become so insane and/or the quality of their affordable models will fall so far through the floor that nobody can justify using them without a national-government-level budget. Gemini will be largely unaffected, because Google already had more money than God and they didn't need to join Nvidia's sales-bribe circle-jerk (they're even making their own TPUs, so they're not dependent on anybody's GPUs). This means that Google will effectively gain yet another monopoly if they can keep their prices reasonable.
Following on from that, businesses will begin to self-host open-weights models. Nvidia are already pushing this angle hard, which should tell you an awful lot about what's coming; that's not because their Nemotron is some great saviour (it's as much of a village idiot for the open-weights world as Grok is in frontier-land), it's because they think they'll be able to pitch a shit-ton of hardware at people pretty soon. Smaller vendors will pop up all over the place, hosting the smaller open-weights models, and token prices will fall through the floor. The "smaller" bit is doing all the heavy lifting; model capability will drop too (albeit not as much as you might think).
Accordingly, those people who've already outsourced the majority of their thinking capacity to Anthropic/OpenAI will suddenly be bereft of their laziness-enabler and won't be able to remember how to do their jobs properly before their employer either tanks or realises there are probably better people for the job out there. Lots of redundancies/encouraged retirements, and suddenly a whole boatload of junior vacancies popping up.
Oh, and local AI appliances for the home will start to pop up at gradually-more-reasonable prices as the DRAM market recovers from its current heat-stroke.
Think that pretty much covers everything. I give it another 6 months for the cracks to appear, and by mid-2028 we should be in local-AI-rules-the-roost territory.
