WTF are GPUs (and why can't I have any?)

MLVC x Rootly Pitch Night, Toronto · October 26, 2026 · 7:27

Austin Baggio, Ensue's CEO, gave this talk to a room of founders at MLVC x Rootly Pitch Night in Toronto on Oct 26, 2026. The first half covers why GPUs are so hard to get. The second half is about why the real bottleneck in ML is how many experiments you can run.
