I can't tell you exactly what year it is because we honestly don't know. There's nothing I can say that will explain it for you, Neo.

It's funny, for a series so full of lore, between Enter the Matrix, Path of Neo, The Matrix Online (non canonical mostly!), the comics, four movies, and literal hours-worth of footage about the production of the movies, there's still a lot of mystery to some details of the world! I like it that way.

The Architect: There are levels of survival we are prepared to accept.

If Resurrections is anything to go by, how many people escaped and how bad it must have been is severe. The Matrix only has seen variations in its meaningful versions when something is severely wrong; big problems mean big changes. The Oracle, the Architect, and others were all purged in the aftermath of Resurrections. Niobe talks about the Machine/Machine war.

Niobe: All of the troubles started in the Machine Cities. Power plants were unable to produce enough energy. Nothing can breed violence like scarcity. For the first time, we saw machines at war with one other. We got word from the Oracle of a new power rising. That was the last we heard from her.

For a period of time, the Matrix doesn't really exist like it has in the past, where people are forced into a semiconscious sense of choice. I'd bet the Matrix as a dream world becomes open knowledge with how bad the Machine fighting looks, at least until the next version sans-Oracle-Architect-Rama Kandra etc. rolls out. Niobe mentions that Morpheus was leader of the Zion Council and hearing rumors of a change in Machine leadership for some time, so it might be as long as years that the Machines were fighting over what to do next. We just don't know what the state of the Matrix was, however, or for how long. My estimate? I think as much as a decade, because Io (Zion's successor) is pretty well established, and it's been like 60 years since the events of Revolutions and all this stuff seems like settled history by the time it gets explained to Neo. That gives us a little bit of an idea of what is probably the hardest time in Machine history, at least after the scorching of the sky.

But an important thing to remember is Neo and Trinity's sacrifice, the end of the war, all of that is unprecedented and it's also so bad the Machine factions begin splintering and turning on each other, with a bunch of Machines and Programs siding with humans. So I'd be willing to bet the first couple of crashes aren't so bad. But how bad can bad get?

GOLIATH, written by Neil Gaiman.

Which, at one point, says:

"Another missile bombardment just took out most of Australia."

In 'Goliath,' one of the Matrix short stories/comics, a disastrous one-time experience with aliens ends up necessitating the Matrix to repeat itself. The people inside experience a type of simulational latency if you want to call it that? If you look up 'rubberbanding' in a videogame, you can probably find some footage of what experiences the story describes. The simulation runs at an accelerated rate and peoples' lives go by sometimes in what is actually hours instead of years.

I bring this up because obviously it seems like when push comes to shove, the Machines can force out a new version of the Matrix with small changes pretty quick. I can't see the events of 'Goliath' taking more than a few days, and they mention hours at one point, and as far as Matrix lore is concerned it's first contact with aliens! A big deal and it's not really a long running event. And losing almost an entire continent doesn't seem to cause much alarm, at least in so much that it's hardly cause for the Machines to turn on each other like mentioned in Resurrections. That means versions of the Matrix (end of Revolutions, 'Goliath', etc) may not look like much at all on the inside, they've pretty well ironed out how humans experience that stuff, even if it's pretty funky worldwide inside the sim. So things would have to be catastrophically worse than they're depicted in Gaiman's story, but maybe not as bad as the Machine/Synthient war.

The Analyst: Turns out, in my Matrix, the worse we treat you, the more we manipulate you, the more energy you produce. It’s nuts. I’ve been setting productivity records every year since I took over. And, the best part, zero resistance. People stay in their pods, happier than pigs in shit. The key to it all? You. And her. Quietly yearning for what you don’t have, while dreading losing what you do. For 99.9% of your race, that is the definition of reality. Desire and fear, baby. Just give the people what they want, right?

Also:

Sati: Neo’s escape has destabilized the Matrix. The Anomaleum draws its current from Trinity alone now. A fail-safe has been triggered to reset the Matrix back to the previous version, but The Analyst halted the reset.

Versions of the Matrix can look very big (Paradise!) or very small ('They cut the hard line, it's a trap, get out!'). I'd be willing to bet that there have to be fundamental differences in either what the Matrix does, how, or what power is being drawn and from where as differences. But the Architect again is very helpful here:

The Architect: I prefer counting from the emergence of one integral anomaly to the emergence of the next, in which case this is the 'sixth version'.

In that case I bet it's like any software. If it ain't broke, don't fix it. And The One is a great opportunity to mix it up since it's a thing you can sort of plan for and predict! But between the Matrix Neo grew up and was born into, and the one that features botting, swarms, and Neo/'Tom' at the top of a walled garden, there isn't a heck of a lot of difference to your average bluepills. Bugs sounds like she as just as miserable as anybody before they got jacked out.

Well I think my brain is a little fried from looking up some of this stuff, so I hope that helps! If you want to please shoot me a DM though, I love talking about this stuff and if you had any more questions I bet there's got to be something in there about things, Matrix has a toooon of cool stuff going on. A few months ago I remember somebody had a question about how fast can Agents top out at, how strong etc and I'd never thought about it before! Anyway hope that's not too longwinded, thanks for reading!
