I actually use Flash nearly every day at work. Legacy support is no joke. We have a multi-million dollar system that is all controlled by a computer that is dual-booting Win11 and WinXP. Because the control program is coded in Flash. It’s coded in Flash because there are a lot of moving parts, and the program displays their current positions. And dynamically moving objects is like the one thing that Flash does really really well. Instead of trying to re-program it in a new language, the manufacturer just fucking ships WinXP. Win11 is on another partition, and is only booted when you need to connect to the internet to run firmware updates on the various motors.
