Another thing to take into account is that even if UI Toolkit is stable enough, it’s still a relatively new system, and there are still lots of games in development that were created on older Unity versions that don’t support it. This means that in order to land a job in this industry, we need to get a decent amount of exposure to uGUI due to most games being created with this technology. This happens because it’s not safe or practical to update an already-tested and working game with new technologies; such changes...
