My guesses are

1. We'll train the LLMs not to make sloppy code.

2. We'll come up with better techinques to make guardrails to help

Making up examples:

* right now, lots of people code with no tests. LLMs do better with tests. So, training LLMs to make new and better tests.

* right now, many things are left untested because it's work to build the infrastructure to test them. Now we have LLMs to help us build that infrustructure so we can use it make better tests for LLMs.

* ...?

* better languages and formal verification. If an LLM codes in Rust, there’s a class of bugs that just can’t happen. I imagine we can develop languages with built-in guardrails that would’ve been too tedious for humans to use.
