I've heard it said (maybe by Frank Zappa? can't remember for sure) that the difference between a professional musician and an amateur is not how well they play at their best, but how well they play at their worst.
There will be many concerts, where you are just at 70% of your peak ability.
As a professional musician, you have to make sure your 70%-version is good enough that people gladly pay for seeing it.
Or you just do electronic music, so that's not an issue!
I saw Brock Hampton at a festival in 2018. Hadn't heard of them before, and they were described to me as a boy band so I had low expectations. Their performance was bizarrely wonderful - they were all painted blue and wearing orange jumpsuits. Anyways, they have a DJ with a Macbook and a bunch of rappers. At one point mid-song they have a bar of silence, and I swear I saw the DJ lean forward and hit spacebar to pause the track and then resume it after.
Also, a lot of other live electronic music performances have almost zero showmanship, so there's that too.
(Speaking as an electronic musician)
To expand upon what you said: it's amazing when you take that trick, a kickflip for example, and you're so confident in your consistency, that you apply it to something new. Kickflip to rock to fakie, kickflip down a set of stairs, kickflip to 50-50, and so on. The consistency you gain from that trick opens up the door to a whole new world of combinations.
There's so much about skateboarding, the culture (or counter culture in some cases) around it that translate so well to programming/hacking (and life in general). The trials of learning something new. The acceptance and overcoming of failure. The respect you shown and earned when you're at the park and you or someone else puts down a sick trick.
One of my favorite creative minds in skateboarding, Rodney Mullen, talks a bit about the relationship between hacking and skateboarding in his TED talk. [1]
