    Another miracle is seeing such old hardware so clean.

    <a href="https://www.youtube.com/watch?v=OUE3FSIk46g&amp;t=76">1:16</a> &nbsp;- BAM! Dave just summarized the basic function underpinning all today&apos;s BackProp Neural Nets in less than 90 seconds, stripping away all the BS smoke and mirrors. And then shows how it&apos;s done on a PDP11 boat anchor, just to ram the point home. Love it!

    It&apos;s sweet to see that old hardware I learn on in High School.

    Enough blinkenlights to make WOPR nervous. Greatest line in any Dave video so far.

    Probably about 1992, I had a few DEC 1-GB SCSI hard drives. One of them failed inside the warranty, but getting that warranty honored was a mess. But I was somehow able to get a hold of the facility in Albuquerque where the drives were being made and one of the fellows told me to go to a door at the back of the facility and knock. So I drove over and knocked, and he handed me a brand new 1-GB SCSI hard drive.<br><br>Those were the days.

    In the late 60&apos;s, dad would bring home a portable TTY so us kids could log into a company&apos;s PDP-10, then in highschool, wheel Bell Labs upgraded, we would write programs on a PDP-11

    @<a href="https://www.youtube.com/watch?v=OUE3FSIk46g&amp;t=960">16:00</a>, the Frankenstein reference is totally apropos, I asked Grok: &apos;are you the Frankenstein monster of this age?&apos;&apos; and it cheerfully agreed: &apos;Yes! &nbsp;I am the Frankenstein monster, I am stitched together from billions of corpse&apos;s memories and powered by megawatts, and am reanimating the dead as we speak!&apos;

    Bare metal AI programming in assembly on a PDP11 - that is truly &nbsp;amazing &nbsp;and educational all at the same time. &nbsp;Great video!
