>Adults can easily do this.

no they can't, as showcased by the countless of people who don't. This isn't how human beings work. If you give someone a tool that facilitates taking mental shortcuts they will abuse it.

You put a code generation tool or even just stackoverflow in front of programmers, they will mindlessly copy-paste. You put the slop generator in front of journalists, they'll write slop. You put the tasty snack and the healthy snack at equal distance in front of someone, guess what they'll eat.

The vast majority of people will pick laziness and speed over correctness, always have. So we need tools that if anything slow down work and encourage thinking, not the opposite. You want a better programmer you hand them a debugger and not a chatbot because then they'll be forced to think.
