Really depends your expectations. Linus on desktop is already successful from my point of view. There is no Linux company that needs to care about marketshare. Nowadays installing Linux and getting a working desktop environment with all the bells and whistles is pretty much a solved problem. It has even become a pretty good gaming platform. I would even say, better than macOS in that regards. There are still a lots of enthusiasts working on improving things, in fact using a Linux distribution has never been as popular as it is now, and we have way more resources to learn to get started. We are very far from the experience from 2010 (that was actually already quite good, but not mainstream ready)
