One of the things I get a kick out of in the clip of HAL singing Daisy is just how much the physical modules being removed look like hard drives being pulled out of a NAS. I could easily think of a much larger version of my Synchrony NAS looking just like that.

BUT: When I first watched 2001 sometime in the early 1990s, I had only seen a 5.25" hard drive, and not on a slider / rails. I thought the inside of HAL was just tacky scifi from the 1960s.

It's only later as I've seen the predictions come true that I've realized just how forward-looking 2001 is. Like the scene with watching news reports on the tablets at breakfast. It wasn't until I watched a video, on my phone, in the late 2010s, that I realized that prediction in the move was 100% spot-on.

BTW, the 4k Ultra-HD bluray of 2001 is awesome.
