It's also terribly inaccurate to say that "most technical people can, over time, "figure out the business stuff" to a far greater degree than most business people can "figure out the technical stuff". If "figuring it out" is akin to having a basic understanding, I think many great business founders have proven they can learn to code on a basic level. Similarly, developers may also learn the basics of business development, sales or fundraising by reading some articles. And, maybe one more than the other. But just as figuring out the basics of coding does not make you a valuable developer, learning the basics of business does not suddenly empower a person with the ability to ask the right questions, communicate clearly, create mutual value between partners, close a sale, negotiate terms, save a furious client, and so on.
Being moderate at any of these things does not a great founder, or company, make. Implying that techs can somehow become good at these things in droves, or easily at all, is drastically underestimating what a true business leader is capable of.
