Turns out software engineering cannot be easily solved with a ~~small shell script~~ large language model.

The author of the article appears to be a genuine ML engineer, although some of his takes aged like fine milk. He seems to be shilling Google a bit too much for my taste. However, the sneer content is good nonetheless.
First off, the "Devin solves a task on Upwork" demo is 1. cherry picked, 2. not even correctly solved.
Second, and this is the absolutely fantastic golden nugget here, to show off its "bug solving capability" it creates its own nonsensical bugs and then reverses them. It's the ideal corporate worker, able to appear busy by creating useless work for itself out of thin air.
It also takes over 6 hours to perform this task, which would be reasonable for an experienced software engineer, but an experienced software engineer's workflow doesn't include burning a small nuclear explosion worth of energy while coding and then not actually solving the task. We don't drink that much coffee.
The next demo is a bait-and-switch again. In this case I think the author of the article fails to sneer quite as much as it's worthy -- the task the AI solves is writing test cases for finding the Least Common Multiple modulo a number. Come on, that task is fucking trivial, all those tests are oneliners! It's famously much easier to verify modulo arithmetic than it is to actually compute it. And it takes the AI an hour to do it!
It is a bit refreshing though that it didn't turn out DEVIN is just Dinesh, Eesha, Vikram, Ishani, and Niranjan working for $2/h from a slum in India.
I think the timelines don't quite match for that, when Windows 11 came out the LLMs couldn't even output code that compiled more than half the time. However, the moment I've learnt the start menu was coded in React I knew the age of ~~man~~ Windows was over. I don't know how good the guy behind it was in internal politics but everyone on the path from the idea to pushing it to main should be tried for treason and sent to hard labour (debugging the Azure web UI).
I think this was the good old artisinal vibe coding of the previous era, where you still had to not care about quality manually.
