I switched to Ubuntu on my main machine a few years ago. This is my second attempt. There are still some annoyances I run into, the biggest being that the dock regularly disappears after sleep. How would I ever set my parents up on something where even the most basic features require fixes like this https://leimao.github.io/blog/Ubuntu-Dock-Disappear/?

That dude’s bio is... brutal.
“I was a Ph.D. candidate in the Department of Biochemistry at Duke University, working on DNA repair mechanisms. There, after spending almost four years, I systematically proved that most of the projects, theories and guidance from the advisor, which I was forced to do and obey, were wrong. To me, a sound Ph.D. degree or research position job title does not tell anything about the person’s capability of solving a problem and whether the person is a true scientist or not. I have already proved that I am better than most of the people there. In 2016, I decided to leave Duke University, with my own glory, without a Ph.D. degree.”
