AI makes tech debt more expensive

"Companies with relatively young, high-quality codebases benefit the most from generative AI tools" - this is not true

The codebases that use the MOST COMMONLY USED LIBRARIES benefit the most from generative AI tools

True. Also, the LLM will give you the most widely deployed versions encountered in the wild (during training).

That means one might find themselves using deprecated but still supported features.

If LLMs came out during the Python 2/3 schism for example, they'd be generating an ever increasing pile of Python 2 code.
