Thanks!

Regarding food vs jobs, I think it's not a very good analogy because

a) almost every job has a lot to it that could be interesting for anyone

We are not limiting all jobs to "Wordpress site template maintainer for small e-commerce sites" or "MySQL DB engineer specializing in scaling and indexing databases with mostly JSON-based tables". If you are a front-end web dev, you could choose to end up specializing in front-end driven analytics or SVG drawing or something higher-level like d3 plotting or anything in HTML5 games or photoshop-to-code conversion or migrate to photoshop-based design etc etc

B) The goal is not to maximize diversity of food or diversity of jobs. I am not implying avoiding increasing specialization.
