Marc Andreessen who according to wikipedia has had a single employee job in his entire adult life, after which he went on to found a string of companies and then became a VC? Why would I want to take their advice on skills that make me more valuable to an enterprise?
I'd 100% take advice from him on founding companies and on investing btw, but advice on how to build your career as an employee seems wildly irrelevant coming from him.
Why would you ever want to be an employee? Pretty much everything about the American system is setup to shaft them.
The advantage of Andreessen's perspective in that blog series is that he thinks of a career as a portfolio of investments, each of which has their own risks and their own upsides, and each of which may unlock future investments. In my experience this has been a far more effective way to manage your career, simply because everything about present-day America is setup to screw people who take one job and work within its strictures.
