this is a necessary and critical ROS topic. (pun intended). As a newbie learning ROS2 Jazzy (2 months in), and still not having built a real robot, I resonate with many of these points. One thing I will add is it needs to be made more clear what development environment is best for getting started with ROS. In short, after experimenting with getting ROS working on MACOS, Windows, WSL2, and a dedicated Ubuntu machine, it’s abundantly clear that a dedicated Ubuntu setup is best for a beginner wanting to learn ROS end to end (software to real robot hardware). And not on a raspberry PI as many youtube tutorials would suggest, but a decent laptop or PC that can serve as the “master” node.
