We're going to do it.
This article concludes with a hopeful image, but even the picture it paints is gloomier than it is in reality; the economics to seek/leverage modular pieces are there.
Typical web2.0 companies like facebook/twitter/reddit went the direction they went because they HAD to own the whole vertical stack. It wasn't only the rational thing to do, it was the only thing to do to be able to achieve scale and not perish.
This is no longer the case, and that changes everything.
Again, this article concludes with a hopeful message, but the situation is even better than painted in the article.
We still have a lot of work to do, but we have very strong building blocks that are only getting better by the day.
