We all really enjoyed the days when we could throw together a project and focus on the fun parts. Then came all of the other things we should worry about -- security and scaling, which are at least technical problems, but then things like privacy, moderation, and even legality.
It's fun to put up a file-sharing service; it's less fun to think about the fact that it can be used to share child porn. It's fun to have a new chat site with no filters. It's less fun when people use it to plan crime.
We don't want to face that. We want to make it Not Our Problem. And here, now privacy is another one. We used to just gather up user data and we didn't plan to sell it or lose it so why did we care?
The Internet is a lot less fun than it used to be. Or rather, we just managed to ignore a lot of the problems, usually because we weren't the ones affected by them. And so we didn't fix them ourselves, so laws got passed instead, which are never as good as what we'd have come up with ourselves.
So yeah, it's time for people to learn stuff before starting a business. That's no fun. Too bad.
It wasn't always like this, but it is now and for very good reasons.
Sounds like you have to learn something before starting a business.
