Yes indeed. I realize that the way I posed my response was as if I was angry at the person or people and not the last bit there about privilege.
I am quite joyous that the things I like to build and play with are also something aspirational and "exist" in bigger, cooler variants out there in the world. Seeing Space, so to speak, stirs the imagination and drives people in amazing ways sometimes.
It's the unfortunate mechanisms of the world and society and politics and business that partition this in uneven ways that hurts much more. I've met a lot of those very hard working people you describe I think, many times more over than myself in ways I sometimes find hard to admit. But that's what makes it emotionally poignant for me: we're both working hard, have visions, and neither have enough gas to get to the end of the road.
To wit: I can't afford to pay a professional team to design a product around my technology toys, and that likely precludes me in this particular decade from ever making it into something that would "make money" or "become useful" to more than myself. I'd need the "privilege" of living in a city or state where technologically capable people could spend their time talking about software tools and problems with me, and not living between jobs and family demands where that spare time simple can't be afforded. The trap of poverty, as insidious as it is. Someone with disposable income the size of my salary can toss that at a team for a month or two and end up with a shape that quickly evolves into their idea without a second thought.
My struggle - evident in my responses - is not feeling personally affronted when I know it's a nature of the world right now, and that doing what I think as "the right thing" sometimes means being pointed or unyielding in my beliefs. I'm still working on directing that into meaningful discourse.
