We could easily have half a dozen pursuit probes parked in orbit that we could send after these guys in hours. Build four every year and after their tour in waiting send them out to a known asteroid or comet.

Afaik he's never applied at Terraform. Maybe because our process requires explaining the tempering process for screwdrivers for at least 45 minutes.

Hiring X is active recently. I have seen far too many resumes for a moral lifetime. If you'd like to volunteer as tribute to have your resume gently roasted, drop a screenshot in the replies and I'll tell you any subtle goofs that are likely to significantly degrade your ability

This is nature's periodic reminder that we are responsible for running arbitrarily operationally effective space programs. The last time something this large didn't miss us by a whisker it ended the dinosaurs. They didn't have a space program. We do, but ours can't even figure

We can measure the operational capacity of a space program in tonnes per year to LEO. Minimum to be able to do anything about a threat like this is at least a million T/year. Currently at about 2000 T/year. Ngmi?

No part of California is more than 350 miles from the ocean, a limitless supply of water. Every time an official wastes their life advising water conservation, or you drive past 100 miles of broke, fallow farms near the I5, or a city burns to the ground, remember. Water

This is typical degrowth propaganda. Growing food requires water. I like cheap food. It is not a moral failing to grow copious quantities of cheap food even if it occurs out of sight of a Starbucks.

Coming around to the view that, if in doubt, the best way to learn very rare meta skills, is to tackle them in a series of borderline crazy ambitious projects. There's no reading list that will give you this knowledge. You just have to do things, after that you'll have the

I flew through LAX today so took the rare Westside opportunity to catch up with Andrew McCalip at Varda Space Industries and Isaiah Taylor - making nuclear reactors (and his lovely family!) at Valar Atomics. We're building the future in Los Angeles and it's going to be awesome!
