I don't think so. I've started in earnest at 41. It probably takes me a little longer to grasp some concepts, and I have other day-to-day things that take up my time so I can't spend all the time I'd like expanding my skills. Still, starting down this path has already created opportunities for me that I didn't have 6 months ago.
In addition, I think we have to adapt to a changing world. If we don't know how to code, our options are going to decrease pretty dramatically in the coming years and decades.
Completely aside from all the practical stuff, I really enjoying creating things that work. I just wish I started learning sooner.
