I also tried setting my phone to grayscale, but it takes me significantly longer to do useful things, as some UIs are harder to distinguish without color. Have you found a workaround for this?
The issue is that the examples you listed mostly rely on very specific machine learning tools (which are very much relevant and good use of this tech), while the term "AI" in layman terms is usually synonymous for LLMs.
Mentioning the mid-1990s' internet boom is somewhat ironic imo, given what happened next. The question is whether "business models mature" with or without a market crash, given that the vast majority of ML money is provided for LLM efforts.
