Those levels are based on the electronics themselves. Earlier circuits used TTL which needed higher voltages to signify a "High". Newer CMOS based electronics need less voltage.
Lower voltages help with power savings. Higher voltages can and do work better in high power, high noise environments though! 24V as you see is still very popular and useful inany applications.
I am using Claude code to manage my obsidian vault. It is easier because my notes generally break down over time as I’m less motivated to organize new ideas. I use voice to text in the terminal to say things like “add this task to this project” or copy paste in pictures of my hand written meeting notes.
Meta tried to create their own VR and AR specific os, but that project ended up being cancelled. John Carmack was against the idea for a while when he was there. Turns out modifying android was a much better starting point!
