MySpace, ICQ, Altavista, Dropbox, Yahoo, BlackBerry, Xerox Alto, Altair 8800, CP/M, WordStar, VisiCalc, the list is very long.
Also switching email was a lot easier back then. Nowadays if you're using gmail as an auth provider it's very hard to completely abandon an inbox without a lot of friction. Back then all your logins were separate anyway.
I distinctly remember the shift to and then away from Altavista as well.
For now at least, OpenAI has not found a golden goose (i.e. made a lot of money) yet.
in the tech world, maybe. All my 'normie' friends are using ChatGPT though and have no concept of their reputation, nor intention of switching. Most people I know are hardly even aware of alternatives, even of Gemini, though everyone has a Google account.
I personally also use ChatGPT and have zero reason not to, currently. I might switch if they royally mess up, but everything they've messed up has been fixed within a day.
Tesla is lurking as well
