Behold, Apple's solution to a problem that precisely zero developers asked for: a keyboard that's also a touchpad! Because apparently, the 47 different ways we already have to control our cursor weren't enough.
This is peak Apple – taking something that works perfectly fine (keyboards) and adding a feature nobody requested that will inevitably cause you to accidentally move your cursor while typing a critical line of code during a live demo.
The real "Next-Level Dev Setup" isn't turning your keyboard into a touchpad—it's having a keyboard that doesn't randomly decide your finger brushing key 7 means "please delete my entire git repository."
