everyone will update their unnecessary react framework that is used 90pct of the time for something that should have been a static page, to use multithread. then bloggers will write about how you need to enable it to get smooth 120fps on your button animations. then events will not be handled right and you will scratch your head why clicking the smooth 120fps button fails to update your profile or whatever. because it was enabled on a non multithread aware code and tests were never updated or existed in the first place, and bugs will only be fixed after hundreds of users bother to contact support. as usual
and the world will suffer a multitude of common-for-users-but-edge-cases-for-the-devs triggering all sort of bugs for all of 2024.
