Some things wouldn’t be different, you’d still have some instructions on how to make certain drugs, explosives and chemicals. You’d just 3D print more of the components where appropriate, and guns.
If anyone is at all curious, there are plenty of places to download the original Cookbook.
Probably an entire chapter dedicated to 3D printing guns.
Personally quite a fan of the idea of making my own pistol (or, well, some of it) in the comfort of my own home, but far too poor to get a 3d printer that'll actually do a good job.
Best thing in the book was the section on drugs...
"You want to do pot? Here's how to get and do pot. You want to do coke? Here's how to get and do coke. You want to do heroin? You have to be fucking stupid to want to do heroin, we aren't telling you how to do heroin."
Oh, lots of things. But for one thing, Powell wouldn't mock the Colorado River Toad the way he did in the first book (or commenting facetiously about his buddy who suggested smoking toad skins ) since it's an actual thing. Incilius alvarius' defensive poison has actual hallucinogenic and psychotropic properties.
The poison on the back of a typical toad can kill a dog, so be careful, or it will fuck you up. First nations folk would actually lick the toads and just suffer the bad trip until they got accustomed to the toxins. But that's a rough ride.
Since the late twentieth century cultivators would raise and milk toad venom and then distill the desired chemistries into a powder that can be ingested or smoked (much like cannibis, rolled into cigarettes, smoked from a pipe or mixed into edibles), hence yeah, when Powell heard about it, it registered as smoking toad skins though thankfully, the frogs survive the process.
Powell's 'tude about drugs was informed by the 60s mind-expansion movement to try different stuff and see what broadens your perspective. And so the 5-methoxy-dimethyltryptamine / bufotenin cocktail would actually fit right into his philosophy. If I remember right, he talked about trying peyote, which was a really bad trip for him.
All that said, there's self-awareness related stuff that I would want to throw in, since the western psychiatric model is not great for dealing with mental illness or for reconciling living in a toxic society. Drugs are commonly used to self medicate but even then can be so much more effective when we're aware that's what we're doing, and this is a point often missed in drug culture, in recovery culture and in the mental health sector all together.
He also posted an eight-paragraph note on the book's Amazon.com sales page, calling it "a misguided and potentially dangerous publication" and expressing his wish that the book be taken out of print.
[...] he began writing about pedagogy and conflict resolution. This led him to renounce his book and instead campaign for its withdrawal from publication. He was unable to legally stop the publication of The Anarchist Cookbook because the copyright had been issued to the original publisher Lyle Stuart, and subsequent publishers that purchased the rights have kept the title in print. Powell publicly renounced his book in a 2013 piece calling for the book to "quickly and quietly go out of print".
A lot of the same stuff, plus information about how to mine crypto.
As a sidenote: That text file is partially why anarchism has such a bad rep today, because whoever wrote it obviously subscribed to the idea that anarchism means "chaos everywhere and no homework!!11". It's an interesting read, though. I just think the title is a bad fit.
Some kind of unique digital signature containing information about exactly which set of computers it had passed through to get to you, so that every copy would contain information about who distributed it to whom and when.
A lot is still relevant, I think. Additions would probably be on facial-recognition-avoidance and perhaps avoiding surveillance more broadly. As opposed to phone phreaking and other telco stuff, probably more internet and programming-focused things would exist.
I pulled out my copy of the cookbook just for reference, I keep it on my bookshelf next to my copy of the Poor Man's James Bond 2. The 4 chapters of the book were "Drugs", "Electronics, Sabotage, and Surveillance" (The shortest), "Natural, Nonlethal, and Lethal Weapons", and "Explosives and Booby Traps".
I feel like "Drugs" would get expanded upon to showcase more modern stuff like Meth, Fent, Kratom, etc. The electronics/sabotage/surveillance chapter would double or triple in size easily, becoming the biggest in the book owing to our modern times and definitely include info on anonymizing yourself online along with in rallies/protests/riots, using the dark web, and more. Weaponry would get a nod towards 3d printing, maybe stuff on neutralizing gas for protestors/rioters. Explosives and Booby Traps wouldn't change too much.
Going by the type of wrong instructions that were in the original I'm going to guess a page would be all about how to crash the Internet and have an instruction like just type Google into Google.
CrimethInc published some years ago a book entitled Recipes for Disaster: An Anarchist Cookbook that covers their Anarchist view of revolutionary action which they explicitly titled in reference to the old one.
And I think I also saw at one point, someone had collected a bunch of recipes from actual capital-A Anarchists to make an Anarchist Bookbook full of yummy food recipes but I can't find it right now.
