I understand that there are still some pain points for casual users. I first started using Linux on a daily basis in university in the mid 2000s. Back then, even distributions designed for casual users like Ubuntu had problems with everyday tasks like configuring multiple monitors. These days, I don't see any of those problems. I'm pretty confident I could give my parents a computer with Ubuntu 20 on it and they could probably figure out how to do their everyday tasks without any issues.
