This post only says things that are pretty well covered elsewhere, so I’ll just give my thoughts and let you look for evidence/justifications.
Ad blockers are eating the revenue of a lot of sites, especially newssites. This will probably continue because (most) people are unwilling to pay for news.
Companies like the Wall Street Journal and The Economist will continue to exist for a while since they provide domain knowledge that their users are willing to pay for. Admittedly, in this case, “user” is someone who is willing to pay by definition, so this statement becomes rather tautological.
As it gets easier and cheaper to do many jobs in general, from photography (see Gage Skidmore), to blogging about some topic (providing useful info on something), many jobs will become hobbies.
I think ideas like Ben Thompson’s Stratechery will work out. Eventually, we can each be “mini-experts” in something.
Many paid jobs will become unviable. And that’s OK. I think the world will turn out better for it all.
