Corrections:
At 9:44, the default unbuffered channel in Go does not hold any items and has a buffer size of 0. Sends to such a channel are blocked until another goroutine is ready to receive the value. The illustration in the video shows a *buffered channel of size 1* however the overall point still stands.
