I think everyone may have a "ceiling" that is somewhat innate. Some people might be bright but not bright enough to be a Nobel-prize-winning physicist, for example.
But this ceiling is usually only reached after thousands upon thousands of hours poured into something with deliberate practice. So it's pointless to speculate on how "fixed" your intelligence is in a certain subject if you haven't even put 5,000 hours into it.
why not both?

Kind of. The ceiling doesn't technically exist from the nature of neural plasticity in humans, but one does sort of exist because of the time difference caused by people learning slower than others.
Of course you can learn and improve, but that doesn't mean everyone can reach the absolute highest peak because of it. This seems like nothing more than common sense, obviously if you work on a skill you will become more proficient at it.
That whole 'growth mindset' and 'fixed mindset' sounds exactly like the sort of garbage platitude you'd find somebody spouting in order to get a corporation to dump money on some 'workshop' where a dude embellishes common sense in order to make it appealing and easy to sell. It reeks of corporatism.

programming skill isn't entirely equivalent to intelligence and you can be good at programming, especially one particular area of programming, just by pushing yourself to get good at it
although most people have no idea how to get good at it and think that they have to study books or perform exercises and get frustrated and give up
If you can entertain yourself with a thing, you will learn it a lot faster and better than something that just bore you to death.
