Sure. But the point was that if you're a team of 1 engineer, even if your title is CTO, time spent learning "how to be a CTO" when you don't have any team whatsoever is time not spent building the prototype that needs to demonstrate $XX value/growth by YYYY-MM-DD in order to survive.
Learning is always encouraged, but you should be learning to solve the problems you're about to face. Learning to solve problems which aren't going to be obstacles in the near or mid future isn't helping you in your immediate circumstances. Sometimes the immediate circumstances aren't much of a concern, but when they are, you need to be sure you're learning with that in mind.
