It's still possible to let users already type from the beginning, just delay sending the characters until checks are complete. Hold them in memory until then.

Instagram was uploading the images while the user were adding post details, back in 2012!

No one seem to use or care about their own product anymore. Only uses dashboard and metrics, which does not explain the full situation.

That makes total sense from a UX perspective though, the ChatGPT thing does not.

there were a lot of helpdesk chats doing the same, so you could see users typing messages, then deleting words, etc before hitting send.

This was actually one of the reasons why Instagram felt smooth.

Another thing but Facebook/Instagram have also detected if a person uploads an image and then deletes it and recognizes that they are insecure, and in case of TEENAGE girls, actually then have it as their profile (that they are insecure) and show them beauty products....

I really like telling this example because people in real life/even online get so shocked, I mean they know facebook is bad but they don't know this bad.

[Also a bit offtopic, but I really like how the item?id=3913919 the 391 came twice :-) , its a good item id ]

I wondered if ChatGPT streams my message to the GPU while I type it, because the response comes weirdly fast after I submit th message. But I don't know much about how this stuff works.

Likely prefix caching among many other things

I just checked the network inspector, the only thing it does per key press is to generate an autocomplete list. It doesn't seem too hard to wait with the autocomplete generation until after whichever checks you run pass.
