Yeah, that was a weird way to describe the algebraic numbers. The formal definition (those numbers for which a finite polynomial p exists with p(x)=0) is not that complicated, is it?
I’ve always said that one key difference between British English and American English is that a British speaker will intentionally mispronounce a foreign word, while an American will attempt to pronounce it correctly but get it wrong anyway.
Indeed, it’s a simple matter to figure out what you want if you’re buying a Mac. Laptop vs desktop. For desktop: integrated screen or not, for laptop, screen size, weight, then pick your processor, memory and storage and it’s done. There aren’t confusingly named and positioned overlapping models that it’s unclear what you’re gaining or losing for each one.
That’s because PC manufacturers compete on spec sheets and how much does the trackpad suck isn’t one of the numbers on the spec sheet so they don’t care.
From all the reviews, those of us who are skeptical of 8GB of RAM are very much wrong (I’m guessing it’s lingering PTSD from being stuck on underperforming systems with too little RAM that makes us buy much more RAM than we actually need). I’m inches away from buying a couple of these for my kids.
Back in 2000 I got the M1 Air with 8G of RAM (needed the cheapest Mac to test some arm64 stuff) and that laptop served me very well. I never felt RAM-limited. I was always expecting to run out of memory during a big Bazel build or something, but never did.
It isn't the most powerful computer in the world but I never ran into any problems... so it's probably an OK compromise for most people, especially in the world where RAM is scarce because of AI datacenter buildouts.
The M1 Air would have blown people’s minds in 2000. 128MB of RAM was luxurious at the time for a laptop. In 2003 I borrowed and bought several sticks for a presentation (senior thesis on 3D presentation software), and got to 1GB in my desktop and felt like I’d broken some law of physics.
Shortly after I had a TiBook (PowerBook G4) that was _only_ 1-inch thick! Compared to 1.75” Dells my coworkers had, it seemed like the future. DVD drive, modem, Ethernet, full sized DVI port, FireWire, WiFi, Bluetooth, optical audio in and out, gigantic display with a bezel that was unrivaled for years, even among Macs. What a beast!
(I know you meant 2020, but it’s fun to think about the air in 2000).
I have a 2008 iMac with (I think) 16Gb of RAM which is used for just Firefox. I've been meaning to upgrade it to Linux but that generation didn't boot from USB, need to burn a CD.
All our intel MacBooks now run Linux just fine. The oldest is 2012, with 4Gb but most are 8 or 16Gb.
I would always recommend more RAM first over a faster processor; back when I would build desktop machines for Windows, I would use the second best CPU and put the savings into RAM.
I have an M1 MacBook Air with 16GB of RAM. It’s a great computer, but even on days where I’m doing fuck all but using the web I can pressure that memory easily. I also have a tendency to never reboot until that becomes the fastest way to fix whatever performance bottlenecks I’m running into.
I’m not saying you can’t get away with 8GB of RAM. You can, but I won’t recommend a Mac with only 8GB of RAM to anybody for a few reasons: 1) even normal users just using the web will find RAM to be the bottleneck and that will degrade their user experience over time. 2) they’ll spend $600 and even if RAM isn’t as much of a bottleneck for them today, with modern web developers and modern web browsers, it will be much sooner rather than later. And everything is a web app now.
For $600 in 2026, your computer shouldn’t be a bad experience in any way nor should it last less than 7 years and still be a kickass experience. Ideally it should last longer. The Neo is great for what it is, but the RAM is the deal killer for me.
I have an M2 Air 24GB/1TB that has been such a beast that I haven't touched my 16" Pro in months. I have four browsers running, with a ton of tabs in Brave (daily driver) and I'm sitting at 21/24GB utilization with all sorts of apps running (granted, Docker is not at the moment, but it still doesn't make it sweat). I had ~8 pro laptops in a row going back to the late 2000s, but Apple Silicon has changed how I work. A future 14" OLED that was similarly light might turn my head, but if I had to replace it today I'd just buy another M5 Air with at least this much RAM. [FYI I never installed Chrome after M1 came out. Brave has been rock-solid for over a half-decade now.]
24GB is definitely solid. 16GB is like my minimum recommended for any kind of Mac, but if you can go for more you should go for more. I think 24GB should last a good long while though.
Over the years since the M1 has launched I’ve cycled through Firefox, Safari, Arc, Zen, Orion and Vivaldi. For the past year my primary browser has been Orion on one M1 Mac, and Firefox has been the main on another M1 work machine for the past 5 years with frequent dips into Chrome on that one, but I don’t leave it sitting in the background when I’m done with it either.
What actually kicked off my browser exploration on the personal was dissatisfaction with Safari’s performance, and 20 tabs or less was enough to make it drag at the time even with disciplined use. I don’t think it had any significant advantages over a Chromium-based browser that particular year except probably battery life but battery life has not been an issue for me these entire 5 years. RAM and swap are something I do end up monitoring more each year (and I’m not in Tahoe yet for either of them), but I’m planning to drive these into the ground before replacing them.
Safari is the highest for 10 tabs but second-lowest for 20? This reads like AI slop, but even if it's not, it's definitely blogspam with no methodology.
in practice, I can have ~infinte tabs in Safari on my M1 MBP. I'll have multiple windows with hundreds of tabs open and I've never seen it stutter once.
It's actually enabling my worst tab-hoarding tendencies. In the Intel days I'd pay a performance price at some point and have to tend to my tabs, but now they just keep propagating....
I have an M2 MacBook Air with 8GB of RAM that I bought three and half years ago. For browsing the web, listening to music, watching TV and movies, using Gmail, Google Sheets, Google Docs, etc., it's still perfectly fine.
OTOH, for my development Mac, I have 64GB of RAM. (Though 32GB would probably be fine.)
OTOH, for my development Mac, I have 64GB of RAM.
(Though 32GB would probably be fine.)
32GB is starting to feel like a minimum for a common workflow: Dockerized development + git worktree + Claude Code or equivalent for working on multiple branches at once.
Definitely brings our engineers' 24GB MBPs to their knees primarily b/c of the RAM chewed up by those multiple Docker instances.
Will 32GB also start looking paltry soon? It's hard to say. I want to say the realistic upper limit is 3-4 simultaneous worktrees for a given developer (at this point the developer becomes the bottleneck again?) but it's a wild guess that may be hilariously low.
Weird .. I easily run 40 docker containers on an 8GB MacBook just fine!
(Just posting this to show that you have to be very specific when talking about these kind of things. Yeah maybe you need 32GB because you run some large deployment 3 times. Others mayb be totally fine with less if they just develop a basic Python web app. Who knows. The devil is in the details. Omitting them makes the discussion ambiguous and just difficult.)
I don't doubt that 8GB is enough for most uses today. But is it closer to "more than enough" or "just barely enough"? Seems unlikely to be the former at a price point this low.
Five years from now, I have no doubt that the processor will still be fine for most uses, but I doubt that 8GB will be. Especially given that some of the most common memory hogs aren't under Apple's control (cough Chrome cough).
A $600 laptop bought new should absolutely still be useful in 5 years. It should be useful longer than 5 years. That people’s standards are so low is a condemnation of the modern computer market.

Mac devices have been able to get away with less RAM (and higher priced upgrades) for well over a decade. During the Intel era, they were the first ones to adopt SSDs as the default option while everyone else still installed spinning rust. That alone provides for way faster swap storage to conceal a relative "lack" of RAM.
And when they went for their own fully integrated stacks of soldered RAM and SSD? Then everything went off the rails - close proximity and no sockets means very low latency for both RAM and persistent storage on one side and on the other side it also allows for much higher bandwidth because of much cleaner signals - remember, even at "measly" hundreds of megahertz you're already in the territory requiring precise PCB design.
On top of that, macOS's scheduler seems to be much, much more efficient and outright better in constrained RAM (and CPU) settings to provide the feeling of "the system is still responding" than either Windows or Linux. The only setting where macOS goes into molasses is when you not just run out of RAM but of free disk space as well.
Those would be characters set with lead type. Most twentieth century designs would be created using a pantograph to engrave matrices for casting type although traditionally, a type designer would engrave punches which would be essentially the characters engraved at printing size, then struck into a blank matrix for casting the type.
You’d be surprised at the numbers of people living middle-class lifestyles with negative net worth. Credit card debt, car loans (with a too-small down payment, a car purchase can easily cause one’s net worth to decline the second you take delivery on the car), underwater mortgages, not to mention student loans.
The kids really have no idea how tenuous computing in general was back in the olden days. Some of the stability issues in the 20th century translated to modern systems would be akin to black smoke coming out of your computer if you happened to have the wrong two programs running at the same time.
I am no kid but screen(1) dates back to 1987 and any wise sysadmin would put that advice on every ~/.login or /etc/motd so the user could run 'screen' at login, some keybinding to detach screen(1) and 'screen -r' on coming back by telnet.
I never used screen back in the day (I was primarily a VMS guy then), but that man page is one of the best-written man pages I’ve come across: informative, friendly and just the right level of detail.
