A lot of professions are involved in bridge building but specifically architects come to my mind. Anyway, building bridges sounds so fucking interesting, like these things are huge, can hold literally tonnes, forever change the life of people around them, and they can be seen from far away.
Lemmy’s user base is pretty interesting, you will find interesting discussions in pretty much most communities. However, if don’t find something interesting, don’t be afraid to start a discussion on your own. Coming from Reddit I used to be afraid of the harassment, but Lemmy is a safer space ❤️
Some general pointers:
Sometimes yes, a lot of us feel isolated, struggle with socialization and connecting with others. Othen it helps to find other ND people, they are just as interested in whatever niche topic you are thinking about.
PS Yesterday, I started a post on AskLemmy after pondering about how technology and science is changing at a faster pace than people (mostly professionals) can adapt.
