I don't think many would disagree that most businesses fail. Which aligns with the author you disagreed with. So what exactly was your source of disagreement? Make it profitable anyway instead of picking a more proven market/audience?

Not all investments are created equal. the bigger Startups convince rich people to give them millions to work on their idea. Publishers completely invert this; you show them a product and you get a piece of the pie in exchange for them distributing. One's a much safer bet even if everything falls apart. And in the corner, entertainment is pretty much the biggest gamble. Always was, probably always will be.
