You mean the history where MS captured the OS, Applle/Google the phone, Google capture the entire search market for 20 years, Facebook the social web, Amazon shopping, NVidia/AMD, Netflix, Spotify, I could go on and on and on.

Most things in tech settle into monopolies or duopolies.

LLMs are more akin to the search market than the database market. They need to be updated constantly.

Selectively picking out the one technology that's basically no-one's primary business is an odd way to try and convince me. It must be over 20 years now since any large company consider a DB to be a significant product.

Open source winners like Linux and MySql/Postgre are the oddity, not the norm.
