The intellectual labor of thinking about an essay, drafting it, editing, and revising it is much higher than strategically re-typing a ChatGPT output. One requires experience, knowledge, understanding and creativity, the other one requires basic functioning of motor skills and senses.

You could program a robot to re-type the ChatGPT output into a different word processor and feed it parameters to make the duration between keystrokes and backspaces fluctuate over time. You could even have it stop, come back later, copy and paste sections and re-organize as it moves through and end up with the final essay from ChatGPT.

Doesn't sound like it to me. Researching a topic can be a lot of effort, while typing is easy, even with occasional rephrasing. Hell, even with constant rephrasing it's not very hard.

Not when someone creates a browser extension that you run while using Google Docs, feed the entire ChatGPT doc into it and it recreates the doc over a 2 hour period with small bits and pieces.

It sounds a lot easier to retype what you see rather than to create it.
