Welcome, Momo!
Well, hardware is always advancing. It's kind of frustrating if you want to stay in the Apple ecosystem, yet you see that Windows laptops outperform Apple's top machines in both specs as well as in benchmarks. Wasn't Apple supposed to be top-end of the market?
Of course, that frustration doesn't take into account the fact that Apple has a superior feel in many ways (trackpad, screen, general fit&finish) and that it manages to push its hardware to the limits without heat problems. For me, those are as much part of the "top-end" positioning as pure specs.
Yeah, the photography world is very good at that, too. I've been into more artisanal surroundings (drawing, painting) and the same thing happens there ("This brush is so much better than that one!"), but on a much smaller scale. It seems to be the case that when technology is involved, people start overestimating the equipment. Of course, Henri Cartier-Bresson and Ansel Adams used way worse equipment than even the current iPhone cameras. And yes, you can do pro photography with an iPhone alright. Or with a Lomo. Just like you can train neural networks on an Intel 80486. It's just much more enjoyable or practical with better gear.
In my opinion, people overestimate the trade-offs that have allegedly been made. Yes, the battery is smaller (but battery life is the same). Yes, the keyboard has problems (but many people actually prefer it).
I used to be in the PC builder camp. I bought decent CPU, memory, storage that I needed now. When I needed to upgrade, prices were better. But nowadays, I can't be bothered. I'm firmly in the "buy now what you need in 3-5 years" camp now.
