Not really a myth. I do full-stack development. Anything from Ops (will happily configure and deploy to AWS with various CM tools, will set up centralized logging, will set up and configure alerting and monitoring), to DB (been a postgres user for half a decade, dbs with hundreds of gigs of data) to backend (single-handedly built my own Rails-like framework that we used to service millions of users) to frontend (can sling together anything from raw DOM to Backbone to React). The downside is that I'm not really a hardcore expert at any of these things, so any good specialist from any of these areas will be better than me. My role is best for smaller teams spinning up new projects, not as much where you'd need the top 1% professional in a certain area. Definitely wouldn't hire myself if I needed a specialist in a specific area.
