If your goal is to become a tech entrepreneur, then yes, learn to code.
If not, and if you're coming from zero, chase your idea down with HST to prove it's viable before spending all that learning curve time coding it.
These people would have better time building up sweet and clean prototypes ; at least they would have a professional competency at the end.
Because yes, hacking shit together is not a job. Those little hackers that existed 10 years ago all went on to college to learn architecture and what not and are now recruited either for data job, management, or devops / security.
I get the point, I passed trough this "phase" ; but let me be clear : everybody told me it was pure bullshit and shitty software.
Iterate on architecture rather than feature. At some point you gotta be lucid about what you are doing, and hacking sh*t together doesn't help you master the service you are going to expose.
ps : Hacking stuff together is still a lot of fun for newbs or "fun" prototype ; nothing professional or client worthy can get out of this kind of mess.
