    > Especially a tool like RViz is always missing. And in many many robotics video I see (of a moderately complex robot), there's ROS's RViz on some screen.

    I would love the future robotics development stack to be more modular, so that (for example) future middleware solutions don't need to also bundle their own visualization software. This was direct inspiration for creating Foxglove Studio[0] for visualization and MCAP[1] for logging - both work great with ROS, or equally well without it.
