So where is all this silo stuff headed?
Imho there's a right way and a wrong way.
The wrong way is they're each going to divide things up the way Netflix and Amazon divide things up. Or each of the TV networks. Or the airlines or banks.
It'll be easy to link within each of the worlds. The way when you say @davewiner on Twitter it takes you to my Twitter profile and when you refer to me the same way on Facebook, you get my Facebook profile.
Ideally, I should be able to post the JSON file address for this post on Medium, and then all changes would automatically percolate through to readers who get to the story via Medium. And ideally, Facebook and Google would also understand that format, and we're back where we were before all the silos formed.
Any of them could do this, easily, if they weren't trying to exclude the other tech giants from their world. Because that's ultimately how they expect to reward their shareholders.
Or they could simply be part of the web instead of trying to divide it up between them.
This is not an idle concern. This is what businesses do. And if you think tech is different, trust me, it's not. The people who run tech think exactly like the people who run oil, or airlines, or banks. Time passes, tech was never actually run by the renegades of Steve's famous commercial. that was just good advertising. The geniuses in tech are really good at chutzpah and hubris as much as creativity.
Anyway, it's all up to you -- if you want to have all this stuff work together, I believe you can have it, you just have to focus on it, and think and act in your own interest.
