I am a fullstack web developer / project manager. I have just tried to mentally compare a MacBook Air that I have now, with an HP from the 2000s that I used to borrow from my mom a lot when I was a kid. Honestly, I can't think of a single feature that lets me do my work much better (and yeah, I'm taking the performance increase in 20 years for granted here). Yeah, the touchpad and the screen are infinitely nicer than they were before. But if I hadn't ever tried a high-resolution screen, I probably wouldn't have minded. The biggest improvements seem to have come from everything surrounding the laptop — software, internet infrastructure, ubiquitous mobile phones, etc. - I have internet connection everywhere and it's virtually unlimited. - I can buy a server with one click for $5/mo. - Modern browsers can be used to instantly deploy nearly desktop-grade apps to everyone. - Very advanced tools (languages, libraries, IDEs, databases) are free. - Not everyone has internet connectivity all the time, but the niche of only serving always-connected people is big enough that for a while (or several years!) I can just not care about offline mode at all and not solve the hard problems that occur there. - Things that don't impact my work as much but do impact others' work: high quality video calls, free map services, free translation services, good TTS & voice recognition, fast OCR, ubiquitous TLS and fairly common E2E, very cheap storage, etc etc etc. Perhaps the only work-related improvement that comes directly from my laptop's hardware (again, not counting performance!) is CPU-provided virtualization support. I don't know whether a 20-year-old laptop could run Docker, but.. probably not. Without Docker, matching production and dev environment would likely be much harder.
