I always wondered how these kinds of ideas even survived the initial laugh-test. Like, didn't the entrepreneur even have a single friend who could point out how awful and flawed their idea was before they tried to make a serious business out of it?

People used to come to me to validate their horrible business ideas. "Oh, you're a tech guy and you have a business degree! What do you think of my Online Store For Cats idea?" Usually they didn't like what I had to say, and eventually people stopped coming to me for advice. Now I know why these things don't get filtered early. Entrepreneurs tend to be positive and optimistic, and then only surround themselves with other positive, optimistic people. So, now subscription-based juice squeezers make it all the way to production and then people scratch their heads and wonder when they fail.
