It's an 18 minute interview, and the show notes are detailed and timestamped. I especially liked the references to the Singularity project.
For those unfamiliar, Gary Bernhardt is the same guy who did the famous "Wat" talk on JavaScript: https://www.destroyallsoftware.com/talks/wat

I guess this is in a way a response to Bret Victor's "The Future of Programming"? https://vimeo.com/71278954
From about 14:40 he gets animated, basically conducting! Would love to know a programmer's explanation for the function or purpose of arm waving and hand signals in a presentation. Not knocking, just curious!

I knew that it was a string. If you listen closely, you'll hear that he asked "is that an array of object?" He probably asked that because it's in square brackets. I said "No, it's just an object". I've probably seen twenty people call this "wrong", which frustrates me. It's not wrong. It was a stringified object! I didn't say "stringified" because it wasn't relevant to the question of whether the object was in an ar…
It's only 15 commas man, 15 commas. That extra comma could kill someone. Speaking of which, why does WAT do different things on node.js?
Only in old versions of Internet Explorer.

I didn't want to go into this level of detail in the talk, but... I think you still want the MMU enabled, just not used for process isolation. With virtual memory totally disabled, a 1 GB malloc takes 1 GB physical memory even if it's not touched, you can't have swap at all, memory fragmentation kills you dead, etc. It still has a lot of utility outside of isolation. I don't have a good sense of how the performance c…
There's a new CPU architecture in the pipe(should have good silicon within five years, if their projections can be trusted), and it has a very good design around system calls, and also in terms of virtual memory. It has a single 64-bit address space and only protection contexts, and due to the general design of the system it doesn't require any register push(or registers at all, at least in the traditional sense). In…

Seems he took the Wat talk a little personally, but I'm not sure why he defends {} + [] by saying the first { is a statement... wat?

Because Java, Flash, etc. couldn't easily manipulate the DOM . Javascript won for this reason.
There were other advantages. To write JS you just need a text editor, and it's easy to pick up. To write Flash requires spending several hundred dollars. To write Java requires the JDK and to learn Java.
Javascript just required that you click refresh.
Especially on 1995 technology, that mattered. Compiling Java took a while. I didn't use Flash enough to retain an impression of speed, but it sure wasn't instantaneous.
> xs = ['10', '10', '10'] > xs.map(parseInt) [10, NaN, 2] Javascript is beautiful.
It's due to parseInt having an optional second parameter, the radix, and map passing the index as the second paramater, hence: xs = [ parseInt('10', 0), parseInt('10', 1), parseInt('10', 2) ]
He says several times that JavaScript succeeded in spite of being a bad language because it was the only choice. How come we're not all writing Java applets or Flash apps?
While security is the main answer, it was also that Java and Flash aren't necessarily available. That is, getting them to run on another machine was frequently a huge issue, especially if you tried to put in any kind of complexity. Javascript, on the other hand, was omnipresent and comparatively accessible. It was the least bad option by a wide, wide margin. For a different comparison, I switched from Java applets to…
There was also the version issue to worry about. "Pardon me, Mr./Ms Customer/User -- would you mind terribly going and downloading and installing a 20 MB Java update on your 14.4k dialup connection before using this page?"
Nightmarish, it was.
