There's a proverb that says, for every 3 people walking there's someone who can be your teacher.

This proverb is an actual ‘Confucius said’

The concentration can vary though. There are places I’ve been where everyone could teach me a lot, and then there are the other places.

Often, I find those other places teach me a lot, but not intentionally. Seeing someone's mistakes is easier for me to learn from than explicit messages. Less survival bias, too.

I didn't feel this way when I was younger. YMMV.

Have you tried the 700 or MX4s? In terms of comfort, is QC better?

It's interesting how the author argues that eyes can perceive dark-on-light more, but intuitively one would assume that light-on-dark is easier to discern (like bright lights in the night)

Ultimately the best option is probably a progressive change in colors through out the day.

This is great work. Not often we see posts about using tech directly for humanitarian efforts!
