Ideas are inherently valuable, maybe not financially, but they're valuable to have and valuable to society to share.
It makes me angry that people actually believe ideas are inherently worthless. Or that without any code or implementation they're worthless. It's a meme that needs to die. It's like having your cake and eating it too. Here's a free idea for you to think about and contribute to but it's not enough, you want the outcome without any effort too. So you say my idea is worthless.
Ideas are the precursors of RFCs and ISOs and any thing that humanity has ever accomplished. And ideas are meant to be shared.
People that think ideas are worthless are shutting down conversations about good ideas because of this obsession with the idea that execution is all that matters. And so many ideas die on the grape vine because of this poor attitude.
