I'm sorry. It's the trauma of preaching the virtues of crude but efficient concurrency and similar multiprocessing for many years, in many workplaces, and only rarely meeting anything but distrust, disinterest or uninformed rebuttals like "OS processes are very heavy, can't do concurrency that way".

However, it's a real problem that 'beginner languages' like Python and Javascript doesn't readily do multithread computation, something which has been the default on personal computers for quite a while now and available for at least twenty years.
