Very well put. Tools like this, by lowering the barrier to entry of making software (I'm assuming the best case scenario - that App Maker is a quality product), tools like this expand the pie and make the software development industry larger. Wordpress is the perfect analogy here. And a lot of my best freelance jobs recently have been for companies not traditionally in the tech industry who had a new idea they wanted to pursue, proofed the concept with a Wordpress site, and then once they had some degree of market validation, needed a developer to build it into something more robust and customizable.
