Apr 2302:26:24Tap to summarizeWhat is the Anthropocene? No really, who came up with it, when does it start, and why does that matter? Well it involves nuance, scientific beef, and a surprising amount of freaky little guys. And we all know of some sound effects we love, but what is their history, where are the weird places they've shown up, and what can they teach us about art?

Jan Zalasiewicz ignobel lick, heavily acronymized science beef, a person dabbing is the anthropocene GSSP (or fossilized air bubbles in ice), Jan vs Jan, maybe the anthropocene is just an Event, insects are the canary in the mass extinction coal mine but they’re also not in the record, humans make up a third of the mass of large vertebrates - and the rest are mostly things we eat, a t-rex wishes to be the most abundant species and a monkeys paw curls, chicken bones in the fossil record, we’ve pushed back the next ice age 50,000 years, don’t clip me dabbing at nuclear weapons, when does the anthropocene start? 1952 with the plutonium shift, there was a most popular album at the start of the anthropocene, era dates are changed all the time, a spicy retirement letter, did you ask him about the email - I mean I did, rocks are political, we’re not in the anthropocene but let’s see what happens, make this design juicier please, sound effects can be realistic or symbolic, the siren whistle slip sound, the real sound of bald eagles, sound effects are treated more like a commodity than an art and a history, we don’t know if ancient mesopotamians beatboxed, Ella shredded so hard on the thundersheet she bled, sound effect started in plays, shakespeare and kabuki pioneered realistic and symbolic sound effects, tsuke, the first radio sound effects from the 1921 world series broadcast from Jersey, the walking surfaces at the BBC, 1920s sound effect rooms, sound effect records, who would buy this?
