Revisit this comment in 2 months, 6 months, a year. It’s mainly a matter of when OpenAI allows widespread access to the gpt-4 api and developers have time to build stuff.
Also, shockingly, go back and look at the history of other game changing innovations - cars, microcomputers, even electricity. It took time for companies (and consumers) time to figure out how to use them. This will be no different.
