What items are made better than they used to be?

Computer hardware is constantly improving. Sure, the software is getting worse, but there are good alternatives to that either already existing, like in the PC space, or being worked on, like in the mobile space. Also this is ignoring price gouging of PC hardware.

Display tech has gone a long way since early LCD TVs started being a thing. Granted, I still think CRT is a better technology overall, but modern TV panels do a great job of coming close in quality, while having its own benefits and drawbacks.

Good quality audio is becoming more affordable, with $20 IEMs sounding incredible for the price (Moondrop Chu II specifically) and ~$100 planar magnetic cans being available.
