I actually doubt that there are fewer software developers who have those skills. The software industry has grown by leaps and bounds every year for decades. I suspect there are more than there were even 15 years ago.
What has also happened is that tools have improved at roughly the same rate, and the tasks to which we apply software development have also grown exponentially. So there are jobs that exist today that did not exist 15 years ago, and they just don't need these skills.
