Laugh at your parents fumbling with new apps now. In twenty years that’s you. Stay a learner.

The gap you are noticing is not intelligence, it is how recently someone had to learn something unfamiliar. Your parents were fluent in the tools of their own time and then the tools changed, which will happen to you too, sooner than it seems. How that goes depends on whether you are still practising the skill of being a beginner.

Stay in the habit deliberately while it is easy. Learn one genuinely new system a year, even when the old one still works. And be a little patient with them now, since you are watching a preview.
