I'm not sure I agree. Sure a little coding on the side won't save you. But being able to create something out of thin air, to look at a problem and solve it, that will always be worth something. Problems won't magically go away. There's no one-size-fits-all recipe to run a business, so there's always room for improvement.
I find developing a decent product requires people to be on a proper 'jelled' team.<p>Hiring freelancer may get you a nice MVP. But to build a proper product, you need really good communication between customers and various departments, team work, and slick processes.<p>Cutting code is a small part of a software devs job.

Technology and the arts have accelerated so much in such a short time that we're running out of creative, original ideas faster than the masses can consume them.<p>Coding will remain relevant but most other jobs related to the day-to-day maintenance of mankind's existence will be automated out of existence.
Don't forget that automation is expensive and fragile. It will cost a lot to maintain automated systems and it will cost less to keep people alive. So sooner or later people will just be hired to do jobs that require dexterity and creativity, for a little bit of money, which will be more than enough to buy a comfortable life.
"Temporary job security at best" perfectly describes my situation. I never struggled with the math, nor felt threatened by job automation, but learning how to program and develop apps over the past year hasn't exactly saved me either. My only leads, if ever, are small gigs I find through personal connections. My first and only real job (as a developer) was a nightmare, being asked to fix bugs on cancelled projects to, as they said, "prove myself". The cherry on top was when they decided to stop paying me halfway through. Now I'm out thousands in unpaid wages I have to fight for...
