I can think of a few things that could happen to sink "it's the slowest and worst it'll ever be". Even ignoring things that could happen, I think in general we're hitting a ceiling with LLMs. All the annoyances and bugs and frankly incompetence with the current models are not going away soon, despite $tn of investments. At this point it is now just about propping up this bubble so the USA doesn't have another big recession.
