How many of these are due to LLM wrappers without a clear advantage over ChatGPT?

This AI bubble is like the dot com bubble, where tons of "AI-first" companies will come up and go down quickly. The companies that create genuine machine learning innovation, or that use LLMs as "glue" to complete a full product, will find opportunities to solve problems with new tech that we couldn't solve before.

Probably a combo of AI Nonsense and the long tail from the covid-era funding bubble.
