Touch typing is not super useful. I picked it up naturally over time, but it was just an accident. In general, the desire to type fast is a symptom of insufficient automation.

It is sort of nice to turning your laptop screen red and dim, and code on a dark porch at night (OLED screen required to get real darkness). Just you, the vim, and some fireflies. Your eyes will adjust to the darkness, and maybe you’ll see some animals that you don’t normally see.
