Survey: a third of senior developers say over half their code is AI-generated

In terms of LOCs maybe, in terms of importance I think is much less. At least that's how I use LLMs.

While I understand that <Enter model here> might produce the meaty bits as well, I believe that having a truck factor of basically 0 (since no-one REALLY understands the code) is a recipe for a disaster and I dare say long term maintainability of a code base.

I feel that you need to have someone in any team that needs to have that level of understanding to fix non trivial issues.

However, by all means, I use the LLM to create all the scaffolding, test fixtures, ... because that is mental energy that I can use elsewhere.

Agreed. If I use an LLM to generate fairly exhaustive unit tests of a trivial function just because I can, that doesn’t mean those lines are as useful as core complex business logic that it would almost certainly make subtle mistakes in.

… then you are not a senior software engineer

Neither are you if that's your understanding of a senior engineer
