Why does profit matter? I don't personally give a shit about the longevity, margins or market share of any company invested in the technology, but I am generally in favor of research and development of any technology. In most research it's hard to predict the future applications.

That's not to say development is always smart, or safe, or ethical, just that it has to happen in order to see where this goes. Even if there's an end point it's helpful to know where it is.

Unfortunately, capitalism requires a sacrifice to the economy in order to pursue anything. That's what sucks about this. If we weren't hard wired to justify existence in capital there wouldn't be so much occlusive hype around it.
