I do think that at least as of today, programming (at the level of doing so professionally working on a shared codebase along with 50+ other programmers, not making a mess of things, and doing so 4+ hours a day every day), does require a level of attention-to-detail, abstract thinking, patience, and fitting-concepts-in-the-mind that much of the population doesn't have the aptitude for. I believe everyone who wants to train enough to program professionally can do so, but many wouldn't enjoy it. Talking to machines is really unforgiving. It is getting easier over time though so the barriers to entry are lowering.
