The fact that he repeatedly quotes Eric Ries and Steve Blank makes this article a little hilarious to me as well. I for one am only really interested in hearing stories from actual entrepreneurs who have tried and failed or tried and succeeded. Both are equally interesting to me. Academics who have spent their life in office jobs or espousing theories and quotes about how difficult it is do not interest me. Anybody can write about how hard something is from a hundred miles off the ground, but unless you have actually tried, you don't know what you are talking about. This applies to pretty much anything.
It also seems strange to me that he suggests hopeful entrepreneurs should jump from running a business to something useful, like, learning to code. How original. I have been coding half my life. Coding is a means to an end. It solves some particular problems in one particular way. It is not an end-all be-all panacea that picks you up from poverty and moves you into the upper class. Despite what many people think, particularly in the Silicon Valley startup world, knowing how to code is not required to start a business. It is a trade, just like construction, or plumbing, or welding. The only difference is that coding tools are basically free and relatively new. But the law of supply and demand still governs which products succeed.
