the article also seems overly confident

Anybody writing articles about AI, or evaluating articles about AI, needs to get very specific: what month are they talking about, because if your reference point for "overly confident" is based on where things were 8-12 months ago, that's very different from where things are today, and many times experts in the field project progress to what they expect for the future - that is of course unreliable speculation, but so far most of the reasonable optimism from the last year or two for progress in LLM software authorship and maintenance proficiency has been borne out in reality. I'm not talking about the "software is solved" numbskulls, but the progress in terms of being a valuable tool set the way C compilers were valuable tools to former Assembly programmers - yeah... it's gone there.

I also recall trying to use Borland Turbo C++ in 1991 and abandoning it because it was too buggy, wrote the project du jour in C instead, saved the C++ rewrite for 1996.
