I worked in wearable electronics back in 2013. At the time, everyone was trying to crack wristworn heart rate monitors. It’s a challenging problem to solve: having to detect a faint color change in human skin while ignoring the massive shifts in ambient light from sunlight to shade all while bouncing around on a wrist.

“Come on Nike, it’s not hard to add a heart rate monitor. Just use pulse tracking.”
Same with any game, “how hard is it to detect cheaters‽”. Turns out, very.
Being an engineer, you’ll know that the amount of shit that has to go right to get a single pixel to glow is pretty crazy, some when armchair dickheads that have never written so much as a Hello World say shit like “it’s not that hard!”, it just…
