I think the additional wrinkle with AI is that it's having an impact, just not really in the way these execs are saying. Before ChatGPT, there was lots of speculative investment into SaaS-type products as companies looked for another hit. Now, though, I think there is a general sense that, except for AI, Internet tech (and lots of other tech) is fully mature. This huge amount of investment in "the next big tech" thing (again, ex-AI) is just over, and the transition happened pretty fast. Blockchain, NFTs, the metaverse, Alexa and other voice assistants, yada yada, were all ventures looking for something as big as, say, the rise of mobile, and they all failed and are getting killed basically simultaneously.
I think the scary thing going forward is that, over the past 25-30 years or so, tech provided a huge amount of the average wage growth, at least in the US. Even if AI doesn't result in huge employment reductions due to productivity gains, the number of high quality jobs in the AI space is just a lot smaller than, say, the overall Internet space. Lots of people have commented here how so many of these AI startups are just wrappers around the big models, and even previous hits are looking dicey now than the big model providers are pulling more stuff in house (and I say this as a previous Cursor subscriber who switched to Claude Code).
I'm curious what future batches of YCombinator will look like. Perhaps it's just a failure of my imagination, but it's really hard for me to think of a speculative tech startup that I think could be a big hit, and that's a huge change for me from, say, the 2005-2020 timeframe. Yeah, I can think of some AI ideas, but it's hard for me to think of things beyond "wrapper" projects on one hand and hugely capital intensive projects for training models on the other.
