In the video David says he's building it just because he wants to. It really sounds like his own passion project. No investors. It's a nice position to be in.

Now I don't know this guy in the slightest. One view could be he's just a geek like us living out his dream building cool potentially useful stuff not entirely sure where it will lead.

A cynical view is it's all about $$$$.

Either way it's great HN content!

I should have made clear, my suspicions are not really around the engineers running this, its the people who are less motivated by the original cause that can see $$$ in it.

Thats the point right, most of us would, if given the chance, divert some funding to work on a passion project that could easily save lives. That I applaud and would love more people to be able to do.

We have no investors, we could pocket the money. We're choosing instead to spend it on projects like this <3
