I feel like lots of companies have ditched ROS 1 only because of support being cut and cargo culting about how ROS 2 is better for unclear reasons, but in practice it feels anything but production ready to me. Everyone talks big how Zenoh will solve everything, but the thing is a damn prototype and really goes against the whole idea that having a DDS will be somehow better instead of just adding absurd overhead in both CPU and networking.
I've touched ROS 2 back in 2019 during the Crystal Clemmys era but it still felt experimental back then (and I believe still was considered beta), I plan to re-evaluate later this year/early 2025 how stable ROS 2 is now.
ROS 2 is better in some aspects that weren't accounted for back when ROS 1 was developed (which started as research platform), mainly distributed systems (multi-robot environments) and good tech developed elsewhere that the system could benefit from.
My personal take is that there is a lot of hit and miss between versions, no guarantee that what works now will work on the next one due to the decentralized nature of the community and the fact the team developing all this is relatively small. I would love to have a way to do small iterations on my own stack to bring it to the latest and greatest ROS release, but the combo of ROS 2 + major Ubuntu upgrade every 2 years is maybe too much for my own peace of mind.
