I don't like the word "agent" because it is not a blind LLM, small or fast script. It is a complex workflow with many checks and prompting before writing a single line of code. That's also the key to AI powered development; context.
It's quite possible it's a case of holding things wrong but I think at least the basic evaluation I did that made me come to the conclusion that Go works particularly well isn't too bad. I just get results that I feel good with quicker than with Rust and Python. FWIW I also had really good results with PHP on the level of Go too, it's just overall a stack that does not cater too well to my problem.
My own experience with "Agents" (and no, I am not a luddite) has been nothing short of comical in how terrible it's been. We try it every single day at our company. We've tried all the advice. All the common wisdom. They have never, not once, produced anything of any value. All the public showcases of these brilliant "agents" have also been nothing short of spectacular failures [1]. Yet despite all this, I keep seeing these type of posts, and pretty much always it's from someone with a vested interest of some kind when you dig deep down enough. All the managerial types pushing it, you look deep enough it's always because the board or investors or whatever other parasite has a vested interest.
I know one thing is for certain, what AI will give us is more and more fucking advertisements shoved into every facet of our lives, except now it sorta talks like a human!
