That makes a lot of sense when reading, but in reality a lot of things have snapped back to plain text over and over again.
I don't know the exact reason for that, but it's undeniable that it happened.
Lots of people try completely new novel GUI stuff all the time, always from basic principles. Looks clean and neat but doesn't survive the real world. Meanwhile, plain text tools have been improving and spreading roots consistently for decades.
Could be that a GUI gets some showtime, but wouldn't bet against plain text at any time. It's like betting against spoons.
Yeah, we speak in words, so I'm not saying text would go away entirely. Even in our Marble interface, you can still type follow-up prompts to a task. But plaintext won't be an interface by itself.
