Certain people do tend to have an easier time with skills that make it easier to be a developer, but there is a VAST untapped potential of people that think of our work as "coding" and assume they're unable to learn. We really need an influx of people with systems thinking and other "high-level" abilities—development skills are required, but not the deep technical abilities our field has traditionally prized.
I've worked with plenty of "genius" types who can write advanced algorithms with lightning speed, but aren't able to see their work in a larger context—nor able to explain to others what they're doing. And I've worked with "normal" people (usually with an oversized dose of Imposter Syndrome) who are so much more effective because they understand the why as well as the how, while also being better communicators.
And let's cut out the IQ bullshit until there's a proven link between IQ and ability to deliver business value.
>A growing body of research suggests general cognitive ability may be the best predictor of job performance.
I don't think there's any doubt between IQ and delivering business value. Some argue EQ is more valuable, but that doesn't mean IQ isn't important.
Even given studies that show a link, there's a big difference between requiring a minimum IQ of 85 to join the US Armed Forces (as mentioned in the Wikipedia article on Intelligence Quotient) compared to asserting a minimum IQ of 120 (or whatever) to be a software developer, as amosquito seems to be doing in their comment ("...massive IQ-based barrier to entry..."). Of course there has to be some floor of intelligence to perform the job—but I'd argue it's a lot lower than many in our field believe.
Second, a "genetic bottleneck"? That absolutely reeks of genetic elitism. It implies, rather heavily, that they are genetically superior to those who cannot (or just don't) do this work.
The idea that we are special because no one understands us - finance, biotech, pharmaceuticals... No one really gets those, either.
Software Engineering has a massive IQ-based barrier to entry. Not only that, your advantages are in large part, from a purely technical perspective, are reflected in your ability to consume algorithms, techniques, and hold more variables in your head at a faster rate than others.
It's an incredibly unique union of art and engineering, we are in demand as every industry needs it, and there is a genetic bottleneck.
We suffer from massive privilege because even semi-technical people have no idea what the fuck we are doing, so oversight is limited at best.
As someone who came from being a huge overachiever in a different industry, we are insanely privileged.
