What is the ambiguity here?

If it is live, it is being done in real time.

If it is pre-recorded it was done previously.

If you call a pre-recorded demo "live" then it is fraud.

What more is there to get?

It seems like you're misunderstanding what parent meant by "prerecorded" - not a screen recording, just pre-writing of commands to be executed during the demo. Would you consider it "deception" to hit up arrow a few times in a terminal during your demo to execute a command from shell history? This is effectively the same. Take a look at the linked repo, it's very clever.

The original link for itsalive says it works by making it not live and the op says just as much.

This is very different from practicing a script and you actually doing all the actions in real time. You're allowed to rehearse for your live performance but unless you're doing it live then it's not live.

People also hate lip syncing because it's a deception of being live.

And yet, ~all singers lipsync, because the point isn't to show off what the artist can do vocally every single night, but to entertain the audience, which lip syncing achieves.

  > And yet, ~all singers lipsync

I think your view of the world is much more pessimistic than reality. Live music is quite common and far more prolific than lip syncing.

Live music of professional, popular singers is mostly lipsynced.

Are you assuming or do you have evidence to back up that claim. Because I actually go outside and watch musicians perform. Are you telling me they fake the errors too? LOL

The inputs are pre-recorded but the outputs aren't.

  > but the outputs aren't.

I'm still under the impression that they are?

They aren't.

RTFM

  > Every time you press a key, It's a Live will write one character from the file into the terminal, making it look like you're typing every single command with the practiced ease of a consummate professional.

It's like pressing next on a slide. That's not live. That's lip syncing.

Good god, this isn't that hard man. You're fine to lip sync if you call it lip syncing. Just don't claim you're actually singing when you're not and you're all good. Why is this so difficult to grasp?

I know how it works, I wrote the fucking thing.

The problem is you not knowing what "live demo" means
