Funny, I came here to say just the opposite, that I'm glad algorithmic computing is still a thing in research and that not everything is AI.
Ironically, AI is able to produce research-grade algorithms and will probably become an authority on the subject, helping take more traditional CS to the next level.
I think it would make sense to evaluate if the the 'surgical' rewrites mentioned in the article can be carried out by or assisted by an LLM based process.
