It’s not FOSS, but it uses markdown which is open, so even if Obsidian went down the path of enshitification, you could still (in theory) move your content over to an alternative. I know, I know, plugins, non-standard etc. etc…

I get the feeling that research is circling around consciousness arising from quantum effects inside nerve cells. If it’s not that, and it’s just an emergent property of complex neural networks, then:

• smaller animals are less conscious (note, I’m not saying intelligent) than humans, and
• we are all fucked, because AI definitely is/will become conscious, and when that happens Terminator will come true.
