With those examples though, how would we know ahead of time that they "shouldn't be explored?" They sure looked interesting and maybe even potentially beneficial a couple decades ago.
Now, of course, we know those algorithms warp regular users (and by extension societies). Or... maybe they don't? Some research has suggested that just putting this many people in direct communication with each other is the root cause of the problems we see. There could be other ways to fix those without shutting down the internet. How would we know without more exploration?
And yet, with no functioning Facebook or Twitter account, I seem to have no problem finding businesses that sell the things I'm interested in. Most local issues of actual importance are still mentioned in the newspaper.
Facebook could get their databases and backups wiped tomorrow and I'm pretty sure nothing would substantively change in my life or my work (and I work in tech). Same goes for Twitter. I might be exposed to less second-hand stupidity on an average day.
I see lots of hand-wringing about them being somehow equivalent to power plants or water districts, but to me it seems like a tortuous justification for "make them act how I want them to act".
The issue here is that this outage was a result of all the routes into their data centers being cut off (seemingly from the inside). So knowing that one of the servers in there is at IP address "1.2.3.4" doesn't help, because no-one on the outside even knows how to send a packet to that server anymore.
