I have to admit, I asked ChatGPT to do a TLDR summary because I found the writing meandered quite a bit. I think the overall point is sound:
> "Developers become attached to tools like Vim, Emacs, or an IDE because years of experience make those tools predictable extensions of their thinking. The attachment is less about features and more about accumulated trust, muscle memory, and a workflow built around known boundaries.
> AI coding agents disrupt that trust because they are fast but probabilistic, opaque, constantly changing, and capable of producing more code than humans can realistically review. This shifts the bottleneck from writing code to specifying, reviewing, validating, and operating it safely."
(Note the > is paraphrasing)
Trust is a big problem I'm having with these tools so far. What I've been running into a lot is, I'll get like 40 hours of work done in a day, and I'm like, wow, that really was quick. Then I'll start using the application I'm making more directly (a tool for writing), and I'll start to see that it's broken all over the place in very surprising ways (ie, updating this menu item broke something on the other side of the app, etc.). So then I spend another 40 hours kind of fixing everything that was broken, and at the end of those two weeks I'm like, did I actually go much faster or was that all kind of a wash? Because if I'm not going faster in overall terms, then the loss of deep understanding of the code base might not be worth it if my pace is the same.
I'm sure someone is going to be like "BRUH AUTOMATED TESTS" or "BRUH MODEL CHOICE". I have a LOT of automated tests, and I don't like fussing with models so I pretty much use Opus on high reasoning for most things (or the equivalent from other providers). Code review also doesn't help that much, for much of the same reason it doesn't tend to help find bugs in human written code either.. you're reading the happy path usually.
Anyway I wouldn't say these tools aren't useful, but, I'm deeply skeptical of all the productivity claims because I think people just look at one dimension of it while ignoring all the other important dimensions. Yeah you can generate a lot of crap fast, but most of it is not shippable and making it shippable does take time.
