Does driving a car make you a better cyclist? I don't know :) ....
I help build really large applications. I mean petabyte of data in a week and real-time communications with millions of users and clients.
I still suck at wordpress or writing binary communication protocols. I can use kafka and build clustered docker-boxes as worker systems with apache spark and write asynchronous worker from scratch in 8 different languages.
It makes you a better developer for bigger distributed systems.
The skillset is just different, it's more complex. Did you write a modern react app with redux maybe with worker systems and real time sockets, this is also very complex it is just deemed less special.
Being curious makes you a better developer, challenge yourself on a regular basis. The rest is often just problem domain switching ...
I do recommend building big things, actually I recommend switching through different industries and domains. It helps you gain perspective
Those are my thoughts.
