If the AI is writing 100% of the code it literally is free (as in time) for them to move them over to native apps. They should have used the tokens for that C compiler on the native apps, would have made for a much more convincing marketing story as well.
Seriously, they claim to be able to make a C compiler but they can't make a TUI without using javascript? It's beyond pathetic.
To be fair in that respect, Claude code does have a native rust implementation you can use.
