The title is objectively clickbait though, even if she does eventually explain the design flaw. But I think if she's doing an hour on the history of RAM design, she could be honest about that.

This is probably a matter of taste, but I can't sit through 58 minutes of slow buildup just to get to "ram has to refresh, that takes 300 nanoseconds sometimes, you could eliminate that at the hardware level by making all ram twice as expensive"

Thanks Laurie, but you don't have to pretend all ram is fundamentally broken to make me watch an hour of maths and engineering. 3blue1brown does that all the time with titles like "What is a laplace transform?" and thumbnails of plain formulas on black backgrounds.
