What's with the purism? It's just a term used to differentiate one way of making a UI from another. Who cares about what is practical when you're just trying to give a thing a name.

Even in your example, it's pretty clear cut. If the window is built with text and served in a terminal emulator, it's a TUI. If you build it with a graphical framework that now needs X11 or whatever, it's a GUI.

This is just needlessly pedantic.

Being a few months behind schedule is forgivable for human space flight.

If a SpaceX Falcon blows up on the pad, that's one thing. It's expensive but they accept that risk to move faster. At least they gain knowledge of what failed, to do better next time.

You can't apply that mentality once a human is piloting it however. That's how you get Columbia, Challenger, or Apollo 1.

> a metaverse that no one wanted

That's the thing though, there is interest in "metaverse" style programs. VRChat, the biggest one, got 80k concurrent users last month (all time peak) according to SteamDB. Seems low, but hardware is a limiting factor for them.

What happened is Facebook's version of this was a corporatized, simplified, G-rated fraction of what its competition is. Despite being in a medium where the defining factor is the ability to look out the eyes of anything vaguely humanoid, you could only be a generic human who only exists from the waist up, devoid of almost any self expression beyond maybe accessories or retexturing.

As a result, there was no audience: the people who already use VR aren't going to go to an inferior product. And the people who would buy a VR headset aren't going to waste their time on a ghost town.

> LLMs are basically Stack Overflow on steroids

That, and I've never had to beg an LLM for an answer, or waste 5 minutes of my life typing up a paragraph to pre-empt the XY Problem Problem. Also never had it close my question as a duplicate of an unrelated question.

The accuracy tends to be somewhat lower than SO, but IMO this is a fair tradeoff to avoid having to potentially fight for an answer.
