Also tin and tin plague
Lead free solder dramatically has increased failure rate. Thus INCREASING landfill. The health and environment impact, if electronics is built to last and then recycled is negligible. The prohibition doesn't apply to Aerospace/Military and some watches.
Also gold is unsuitable for consumer connections. Any damp and nearby tin is attacked. Gold should only be used with gold, and if not regularly unplugged. It's not even the best conductor, just corrosion free and pretty, though causes electro-galvanic corrosion in many other metals.
Fan failures over the last 20 years have been a massive source of PSU, CPU and Graphics card failures.
While ceramic and plastic dielectric capacitors are hugely better than 1950s paper capacitors, the Electrolytics are a disaster, modern ones seem to be too small and in places with more heat than a valve radio (they put the caps away from hot bits). I think modern electrolytics are 1000s of times less reliable than 1950s ones.
