> Now, obviously that is not valid Java syntax and javac will fail on that, but could/would it be possible to just build an intermediate tool that'll expand this into Java (or whatever other language) so that you don't need to even see the expanded code in your editor, like the same way you don't need to see bytecode?

One step before this (AI as a pre processor that generates source code which is then validated by tests and committed without even review) I think is possible.

Cutting edge LLM apps utilize multiple LLMs to perform validation, task decomposition, etc. it’s not a stretch that a future application can take your pseudo code / spec, maybe ask you some clarifying questions, generate a bunch of code and test cases, maybe even launch a beta stage and prompt you to validate it.

As others have mentioned, LLMs are nondeterministic and can do the wrong thing on a given run. This is in contrast to a traditional program that is either buggy or bug free. OTOH another LLM can be trained to validate, and to debug.

There’s a lot of work to do before LLM apps are considered reliable enough to do their job without intense supervision.
