We develop them from scratch - they just kind of come to us wherever we are. They aren't necessarily originating from interactions with other people, either. They may come to us at the grocery store, or while we're driving. In fact, there's a high probability that we won't even get the chance to write all of our ideas down, because our activities interfere with the ability to document them. We can't exactly pull out a dictation system (voice recorder) while we are shopping for clothes. In some cases, our ideas are documented in our surveillance systems, which are then later transcribed. But the system isn't automatic. We still must physically and mentally transfer the information into a format that is usable by other people, such as this website. It takes a considerable amount of time.
The reason why you don't see any sources cited, is because these are all original ideas from the MCE123 Company Founder. He doesn't interact with the public very much to get ideas - he's sort of a recluse. He just imagines a future world, and what types of technologies will be in it. It doesn't mean that all of his ideas will become a reality - nor does it mean that he captures all of the ideas. He simply advocates for the advancement of technology through his own thoughts and improvements to existing systems and technologies, just like they have been improved for hundreds of years.
