That should be a shirt
Tesla using Qt for GUI while SpaceX uses Electron shows how crazy modern UI development has become.
As much as Tesla's well known for thumbing their nose at safety, Qt has variants designed for safety critical things like instrument clusters. Whoever owns Qt these days even calls out instrument clusters specifically.
Electron has none of that.
Not to mention how slow Electron would run on the embedded CPU on the Tesla dash board.
The Intel atom is slow but the newer cars have an AMD Ryzen and it should run fine.
I sometimes wonder if the fancy SpaceX touchscreens are there just for the press, and when the cameras go off they use the real physical instrumentation backups that wouldn't die altogether with the wrong helmet bump in zero gravity.
