Did those who advocate for abolition of slavery have intensely detailed plans for how an economy would function post-slavery, complete with successful examples of societies that built some other economic system after slavery?
Marx and Engels spoke just enough about future socialism to provide the framework. They didn’t fill in the details because that is not possible, there is no one-size-fits all blue print for socialism. Each time and place has its own specific context that must be accounted for. Ignore that and you will likely fail.
Also, Marx and Engels whole point was to describe the history of all hitherto society, and how class struggle defines that history. To try and authoritatively say “this is the precise next step” would be undialectical and anathema to their entire approach.
I think there are many valid criticisms of online dating, I would not suggest it’s an unalloyed good thing. However, I am old enough to have plenty of experience (trying to) date when online wasn’t an option (limited only to work, through friends, and through church since I was religious when I was younger) and I have to say, I prefer having the online option - or at least I did before I married my wife, who I met online.
Relying only on non-online spaces sucked for me. I just didn’t have the confidence to approach women and ask them out. I put myself in the friend zone all the time. When I first found online dating, I found it refreshing. It lowered that barrier for me and I think probably for a lot of other more socially awkward people.
There’s probably broader social problems when online becomes the dominant form, at least under capitalism.
Sometimes I get the feeling Zoomers think dating was “easier” before apps but I really don’t think that was the case, at least for me.
