> post agentic LLM as programs are going to be mostly bloated ad-hoc, poorly thought-out and patched in a way that does not concern it's self with the correctness of the algorithms or data structures chosen.

This is an accurate description of 90% of corporate software pre-LLM.

LLMs are introducing a unique kind of bloat and dysfunction but it's not like they are replacing pristine code. Most software that is subject to market pressures and is generating a profit is painful to look at and difficult to work in.
