> A junior dev could build a working twitter clone in a couple weeks; tech was never Twitter's moat.

Aren't we over saying things like that? That's Dunning-Krueger speak. The bits that you see as a user are just the tip of the iceberg required to support hundreds of thousands of tweets per minute that Twitter currently is capable of.

Ya you're right, my junior dev comment was stupid. I think I stand by the tech not being the significant moat here.

he's not entirely wrong though, there's an online bootcamp dedicated to literally doing this, using AWS as the backend, might take more than a few weeks but the point is that until you start to worry about web-scale a jr dev could do the implementation of front-end/back-end in a month or two.
