Yep I hope that mindset never dies. Meta is one of the last engineering-first companies in big tech and willing to live demo something so obviously prone to mishaps is a great sign of it. It's not unlike SpaceX and being willing to iterate by crashing Starships for the world to see. You make mistakes and fix them, no big deal.
One of my internships was preparing Bill Gate's demo machines for CES. I setup custom machine images and ran through scripts to make sure everything went off w/o a hitch (I was doing just the demos for Tablet PC, each org presumably had their own team preparing the demos!)
Not doing it live would've been an embarrassment. I don't think the thought ever crossed anyone's mind, of course we'd do it live. Sure the machines were super customized, bare bones Windows installs stripped back to the minimum amount of software needed for just one demo, but at the end of the day it sure as hell was real software running up there on stage.
The same unwarranted sense of confidence that tells them this product is worth making tells them that they can easily pull off a live demo. This is called "culture fit"
I saw Jobs give a demo of some NeXT technology and the system crashed and rebooted right in the middle of it. He just said “oops” and talked around it until the system came back up.
Totally agree. Up until a few years ago failures during live demos on stage used to be a mark of authenticity, and companies playing recordings was always written off as exaggerated or fake. Now all of Apple's keynotes are prerecorded overproduced garbage.
"At least it's not faked" was my main reaction, too. Some other big-tech AI-related demos the last couple years have been caught being faked.
Zuckerberg handling it reasonably well was nice.
(Though the tone at the end of "we'll go check out what he made later" sounded dismissive. The blame-free post-mortem will include each of the personnel involved in the failure, in a series of one-on-one MMA sparring rounds. "I'm up there, launching a milestone in a trillion-dollar strategic push, and you left me @#$*&^ my @#*$&^@#( like a #@&#^@! I'll show you post-mortem!")
But hey, at least it's not all faked
