I think they are now doing better than ever. And they have been bought out already by Mirantis, unless I missed something.

Podman isn't really a competitor at this point, it's just the "docker at home" NIH project from redhat. It works fine, but docker isn't going anywhere really.

For you. But is it the biggest dash? And what is its intended purpose? I've never seen one that big before.

Well at least crashing drones into trees has never been cheaper hahaha. So it's super easy to get into nowadays, especially if it's just to play around with flight systems instead of going for pure performance.

I think the big difference is that python 3 took over rather quickly once it hit a threshold. There was a clearer path for adoption too: as more major packages started supporting python3, adoption accelerated and eventually python2 support was dropped. For IPv6 it's a lot less straightforward. You could cling on to IPv4 with basically 0 practical downsides in the current ecosystem as everything that supports IPv6 also supports IPv4, and IPv6 only networking basically doesn't exist. Even mobile users with only IPv6 adresses get to use IPv4-only services through some translation layer that every ISP has to provide when running IPv6.

Well I don't think most people choose who they work with. Even if you like your team a lot, you might have a discussion with someone from another team or division, and that's where it's useful to have a good chat history haha.
