In silicon valley, we live in a condition wherein the company could fail at any time. As a developer, most often, we have to learn something entirely new and ship the code for the business. Those challenges are quite enormous with lots of unknowns

I don't think any of these are true. Companies do not fail 'at any time' because of their programmers nor are they saved by them in the nick of time. If there's something you should be prepared to for it's writing code that's less prone to catastrophic failure rather than coding your way out of some disaster. It's not ER Medicine.
