Had Nvidia put their hubris aside for a second (tough ask, I know) and worked to make Isaac into an open source project, it would have eaten ROS' lunch. The subgraph-based approach was much better, the node/component/channel approach is intuitive, and had it been improved upon with better DX, it would be wonderful to use. Plus it used Bazel instead of the godawful colcon. The only good part of ROS is IPC which Isaac sucks at. Sadly they decided to abandon it and repurpose their GEMs as ROS packages instead.
