Replying to
@stefano@mastodon.bsd.cafe Luckily Open Source server side software seems to be mostly immune to Wirth's Law ("software is getting slower more rapidly than hardware is becoming faster"), in fact thanks to easier to use "bare metal" languages (Go, Zig, Rust...) we have a great pick of super efficient self hosted software. People 15 years ago probably wouldn't have believed how much stuff you can host on a simple Raspberry Pi.
On the other hand client side and web application performance nowadays its mostly a joke, having to replace perfectly working phones just to keep using WhatsApp or having Reddit lagging on a MacBook M1 is ridiculous. Open source often isn't much better either since lots of stuff nowadays is still based on Electron and/or bloated React setups.
