That's true, but it's not like learning to code a little makes all your business knowledge fall out of your head. And the point of learning to code isn't that you'll now be the CTO, it's because founding a successful tech company is hard, let alone founding one when you don't know the difference between Java and Javascript. You can still be the business guy, but now you understand at least a little of the core of your business. Not to mention that if you're just a business guy with an idea and no money, few good developers will be interested.
