In this 169th in a series of live discussions with Bret Weinstein and Heather Heying (both PhDs in Biology), we discuss the state of the world through an evolutionary lens. This week we discuss sports bras, Twitter, AI, electric unicycles, and AIDS. Sports bras are a useful item of clothing for women engaged in certain kinds of sports; they are not a fashion accessory, but are being used as such, and as a weapon in the culture wars. Then: Substack announced a new product that will be compete with Twitter, and Twitter responded with chaos; “friendly fire” between two of the few companies that seek to protect free speech is bad for everyone. Also: what are electric unicycles, and how fun and safe are they? Finally: discussion of Celia Farber’s book, Serious Adverse Events: An Uncensored History of AIDS, with some comparisons to what happened during Covid. ***** Our sponsors: House of Macadamias: Delicious and nutritious macadamia nuts, in all sorts of configurations.
