Peter Hutterer's linux.conf.au 2020 talk on creating libinput, the unified userspace input library, and the difficulties of handling the many quirks of input devices.
Why Hacker News points people here: Cited for insight into the hard realities of Linux input handling and libinput's thinly staffed maintenance.

Backs claim that libinput's developer worked alone
