Before I retired, I worked in an industry whose equipment operating software was upgraded maybe every year or two, necessitating the tech group to learn new, sometimes radically different, programming.
Now, I find that equipment in my own house gets new parameters unannounced, sometimes creating a real hassle in relearning. And sometimes it’s an improvement, but that’s not the way to bet. ;)

Samsung should send hello kitty case with the upgrade. Android Pie/OneUI turned my Note8 into a 12 year old girls diary
