Huxley is sci-fi and not reality, and so are your reasons. If you want to avoid a pandemic, invest heavily in biotech. If you want clean energy, invest in nuclear plants and more efficient energy storage and such. If you want to avoid a nuclear war, invest in infrastructure that will allow the world's poor to create wealth and raise their standard of living and not want to kill anybody.

By instead dumping all those billions into space exploration, you are actively raising the chance of something terrible happening here on Earth, this "basket" whose destruction you consider so nonchalantly.
