To try and clarify further: ideas are not worthless, but they also don't have value. How can that be? Simple, unless an idea is coupled with execution its value is zero. This is what leads to the phrase 'ideas are worthless' which is misleading IMO when phrased that way.
> why arent the millions of developers constantly outdoing themselves with utterly amazing work
That statement is flawed on many levels. First, the percentage of the population with a high level understanding of technology is small, and the percentage of those who are developers is smaller, and the percentage of those that are great developers is smaller still. So saying "the millions of developers" like there really are that many working directly on tech innovation in Silicon Valley and elsewhere in the US is questionable at best.
Now, if you're asking why don't the "great" proportion of developers do amazing work the answer is that they do. They are the reason you can view and post on Hacker News with a working OS, or listen to thousands of songs on a device as small as your hand, and on that same device check email, play games, download thousands of apps, and make phone calls, etc. In other words, great developers are busy building things. Many amazing things. Some developers build things for companies, and some venture out on their own to build new and innovative things like Twitter, Groupon, or Facebook, some of which work and many which don't. But there certainly are many amazing pieces of technology that have been built so far, and there are many more to come... These won't all come at the same time, but the tinkerers are out there... building, trying, failing, and trying again. They are doing the hard work of executing, and for a small fraction of them, it will pay off.
Edit: Let me put the idea challenge back on you, phlux. If your belief is "idea" people are certainly only held back from their $ millions in success by not being developers, why don't they borrow, sell, or mortgage $50K on their house etc. and just get the idea built and cash in? It's that easy, right?
