I agree with every single thing about your comment. That said, I wouldn't be surprised if these guys go on to do other things, try again, fail again, try again, fail again, and eventually build something that actually works. It might not be immediately obvious, but deluded entrepreneurs (with their blind optimism and relentless trial-and-error) make the world a better place. I don't know if we should encourage or discourage it, and I'm not too sure if these people can be discouraged either. I suppose at best we can advocate for caution and due diligence.
