Large tech companies like cloudflare are spending developer hours lowering memory usage because they feel the impact too.

The idea that companies should have priority price controlled access to memory puts us even deeper into a situation where we can never afford local compute ever again.

For stuff I wrote that I run on my server, I have been converting from Clojure to Rust. Sometimes mechanically, often by hand.

I actually like Clojure more but even with GraalVM AOT it still tends to take significantly more memory than even naive Rust code (e.g. using Clone everywhere). If you’re looking willing to spend time abusing the borrow checker you can often get memory usage down to like 5% of what you’d get out of Java stuff.
