Why does that matter? You seem to really think one needs objective definitions? It should be clear that whether a definition is objective or not is subjective itself. The question is whether there is some shared experience. And most people agree on what’s simple and what isn’t. You can now argue that’s all cultural, but that’s also a rather ridiculous position. We all experience advanced math as more complicated than 2 word sentences and so on. And I’m arguing, using my experience and examples, that functional programming is unnecessarily complicated.
Requiring objective measures either misses the point. It’s really not a reasonable ask.

I don’t.

Obviously.

Not my point.
My claim is that most people who want to be good software engineers can spent their time better than doing functional programming. I’m trying to disprove the opposite claim. That claim being that you’d learn something important from doing it or that functional programming offers something important to the programmer. I’m simply sharing the result of my journey through it so that others don’t have to make the same mistake. If it’s fun to somebody they should of course do it. What upsets me is that I was caught up in this delusion that functional programming is worth spending significant time on.
True. My statements are meaningful because of that. The objective measures we could agree on are obvious, so they need not to be stated. The heart of the debate is about the things that are hard to measure. As most things in software engineering. I ignored your question because it is a bad one.
> The Haskell looks much better, and I don't even know Haskell
Plain crazy take. The c example uses basic coding to implement some clever maths with special fast instructions. Thehaskell example is just some dumb algo implemented with complicated programming. There is obviously nothing good about that.
The c examples complexity lies in using SIMD. If you know simd it’s easy. You should know simd, it’s useful. The Haskell example is drivel. Long complicated and in the end hopelessly slow compared to the c example. You could als use simd in Haskell, but then it would just be C with extra steps.
Man I hate functional programming so much. Please, to anyone reading this. Don’t waste your time on this stuff. They always try to claim functional code makes things safer and more elegant, but I have never seen that in reality. These ideas seem to produce terrible code first and foremost.

I think exactly that all the time. It’s ridiculous.

I had this problem all the time when trying to write games in Haskell. Not every subject matter decomposes into semirings. Just like not everything decomposes nicely into objects.
People tried to fix this with FRP or lenses. Both are worse than imperative programming for games imo.
I’ve been working with pure functional languages and custom lisp dialects professionally my whole tenure.
You get a whole bag of problems for a very subjective upside.
Teams fragment into those that know how to work with these fringe tools and those who don’t. The projects using them that I worked on all had trouble with getting/retaining people. They also all had performance issues and had bugs like all other software. You’re not missing out on anything.
Most database companies run only a small amount of tests before committing. After committing, you run tests for thousands of hours. It sucks. You probably do this all day every day. You just run the tests on whatever you have currently committed. you kind of have to be careful about not adding more tests that make it take much much longer.
