This week Rich and Matt take a wild ride through the digestive tract of tech as they examine the growing anti-science stance of some of the world’s leading tech visionaries.

And in case you want something fluffy, they round off with the woolly mammoth mouse, a shaggy, golden-haired mouse that might be the first step in the de-extinction of that Ice Age favourite the woolly mammoth.
