I thought about this already for a while and with Lemmy and Mastodon the opensource community has a place to really try itself out and coordinate. Then even things like open-source planning-systems (like at Amazon) and AIs are possible.
At least in Germany there is currently no really political movement that could be described as left-libertarian at least seriously. Maybe the Fediverse could be the root for something like that.
Or will the Fediverse will become more like the new landscape of the internet, which encompasses everything and in which every party will need to move and have a certain stance to somehow?
Anarchism (look it up). Same as the original meaning of just "libertarian", before the far-right in the US successfully took over the term for their version of laissez faire capitalism.
