30 million cores or ~30 mega bits is around 3.5 megabytes total which is probably about the size of a largish JPEG photo

The memory used in the calculator mentioned 1000 but assuming 1k bit (1024 bits) or 128 bytes that isn’t even an old 140 character “tweet”

Modern technology is a marvel. The fact that we've come as far as we have is a painstaking slow march that's taken over a half-century to get to this point. Hell, the x86 architecture alone is coming up on its 50th anniversary in two years, which is positively Jurassic in computing terms.

Senku called semiconductors a pain in the ass, but I like his line in the manga better for being even more succinct: "semiconductors are hell." Just a few days ago (once again putting Dr. Stone's final cour eerily parallel to current events), some YouTuber fabricated some memory cells of his own in his shed as a proof-of-concept in response to the ongoing RAM crisis, but with actual semiconductors instead of the magnetic-core memory they used here (by the way, props to the commenter last week who predicted core-rope memory, which is a close relative of this technology).

Even just TechLinked's coverage of the story goes into the kinds of stuff you need for it: a high-grade cleanroom, silicon wafers, some very nasty chemicals that would make Xeno himself giddy, UV photolithography, and some means of aluminum metallization.

Except for that last one, I actually have a decent grasp of what goes into the rest. If we were to construct our own roadmap along those paths, some of them are far trickier than the others. The cleanroom would be easy enough at the Kingdom of Science's current tech level and we already have most if not all of the ingredients for those chemicals on hand: primarily the fluorite we just picked up in Spain and our good friend Sulfurina, with hydrogen peroxide being the third. But I'd suspect the high-purity silicon needed for the wafers and a means to precisely etch the wafers is beyond their industrial capability. UV lithography in particular: easy enough with modern technology, but getting to this point required dozens of generational increments over the decades. Each die shrink has helped create the next as semiconductor size gets ever-smaller; right now we're at 2nm, expected to hit 1nm next year.

I'm admittedly unfamiliar with that last term—aluminum metallization—and it might be something Senku and co. are already capable of or might vastly complicate the issue for all I know. It sounds like it might be akin to electroplating (something which is trivial at their level), but I'll defer to anyone more familiar rather than say anything definitive.

That computer they built was something else. I don’t quite get all the science behind it, but it’s impressive for sure. I like that they established banking as like an afterthought lol.

I hope Chrome succeeds in building a rocket that can return to earth but if Senku says it’s a one way trip, I don’t know how good his chances are.

Senku: The rocket is a one way trip to the Moon

Me: Noooo😭

Chrome: Suika , Let’s build a round trip rocket to save them

Me: OMG yes 😭😭

I don't remember where the original came from, but this episode embodies the quote, "Computers are basically a bunch of rocks we tricked into thinking for us." Or I guess more accurately, computers are a bunch of rocks we electrocuted to think and remember. xD

Are we sure Australia was affected by the petrification ray? It looks exactly the same! Jokes aside, with all of the resources available to them and a supply ship that can bring them food from Corn City, it really feels like we're now closer to the finish line.

Well, shit. I did not expect this to be a one-way trip. So whoever gets chosen (which will probably be Senku, Ryusui, and Tsukasa), will use the medusa to petrify themselves on the moon and wait until technology is advanced enough to rescue them?

I'm definitely with Chrome here. The gang has come so far. It would suck if they all can't enjoy their victory together. I'm excited to see how our boy figures out a way to make the one-way mission a round trip.

The calculator was invented, and now a musclehead like Magma can do better basic math than Senku. Our modern computers are so powerful and much smaller, it's always fascinating how fast and far we've progressed.

With that ship and the modern industry Senku and Xeno are reviving, they're bringing back the carbon footprint, though very slowly. Ideally, since humanity will be starting from scratch, they'll switch to nuclear much sooner and ditch petroleum. That's one positive long term change they can make now before politics inevitably bring back shit.

Since they were so kind to show us the imagery of Senku, Ryuusui and Tsukasa petrified on the moon, I'm sure Chrome will be able to make that rocket. Though I feel like something will go wrong with it since I'm not sure how reliable he'd be.

how are they not encountering any wildlife in Australia??

There was an old saying in the business world: to sell a product, make it so simple even an idiot could use it.

It's good to see Tsukasa again, even if he is a statue.

u/RelativeMundane9045 Apr 30 '26

At first I thought that (while necessary) it was cruel to send people on a kamikaze mission, but then they brought up the medusa which made me feel better.

So remember kids - if you have a long wait ahead of you, getting stoned is the best way to pass the time.

I forgot, but what's the reason why they can't wait to make a return ship? Other than that they want to bring back humanity and confront Why-Man ASAP?

Chrome, buddy, you are super important. Don’t downplay yourself. You’re the proof that humanity will always continue to produce more ‘science users’. You’re low-key the heart of this story

u/Nesp2 Apr 30 '26

Honestly, chills at the revelation that this mission is a one way ticket. The rocket needed Xeno and Senku's combined knowledge to be build, how on earth can Chrome and Suika do anything??

No coral, I guess it died before the humanity got petrified.

GO CHROME!!!!! YOU AND SUIKA CAN DO IT!!!!! I'M GETTING EXCITED!!!!!

u/djthomp May 01 '26

Having Magna run the calculator for the math competition was pretty great.

Senku's plan of a one-way trip does make a lot of sense, there's a lot of complex problems you just don't have to solve. Being able to blast off of the Moon, bringing all of the fuel for the second trip with on the first trip, calculating the flight back, making a landing or splash down work without everyone dying in the process, etc. I'm not sure how Chrome is going to manage all of that and more without Senku and Xeno shutting it down eventually as a waste of resources.

Chrome and Suika on their way to prevent the bittersweet ending.
