You have the insanity that is geo-engineering which is a case in which you say the planet is heating up. Let's spray some aerosol and cool it down.

I would say that what the value of talking about and thinking about a dome over Manhattan is that [Buckminster] Fuller has identified a scale of action I think is actually really compelling.

I work on everything all at once, which is maybe the worst way to go about it. But I think that actually it works really well in terms of the serendipitous connections between all of these many different projects and these many different realms.

I don't know whether what I do is art. But making things out in the world and having as many conversations as possible.

It isn't a matter of hope. It's a matter of - between the options of trying nothing and trying something, let's try something but let's also be very thoughtful about what that something is.

I set my life since then attempting to figure out how to do that, basically how to have a sort of public discourse in which anything and everything are open to conversation and in which the thought experiment is a means by which to posit all manner of different realities, potential futures.

What we need to do is we need to say, how can - how can we operate independently in terms of putting together these various technologies in order to be able to make the world a better place?
