Doesn't mean the idea is "non-viable"

In fact, it may be precisely the opposite: that it (or something cloesly akin) is being used already generally validates the basic principles of any given "idea"

True, I mean I can't become a millionaire and quit my job.

Just like Sergie Brin and Larry Page couldn't quit their jobs and become millionaires because search engines already existed, or Mark Zuckerberg couldn't quit his job and become a millionaire because social networks already existed :-)

I disagree. I see your posts on HN, and they seem worthwhile when I come across them. You belong where you end up, to a point. Don’t sell yourself short. We can all surprise ourselves.
