M1 Mac SSD and RAM can be upgraded. Also, grass is green.

I kinda agree, though Apple is far from alone in that. A lot of the top-quality PC vendors also sell super-slim laptops in the same price class with just 8GB RAM. :(

I am long, long overdue for new computers (both Macs for my personal use, and now I need a PC for school), and I don’t even like the thought of just 16GB! I want 32GB at least, at least on my workhorse Mac.

Maybe they could do this new thing, where they dont place the memory on the SOC. They place it on this extra PCB, and then it is possible to replace the memory. Maybe they could do this to, IDK, the SSD, the memory and the wireless. Or how about a replaceable battery pack. Or a replaceable CPU. You know instead of soldering it to the MB directly, you have some sort of mechanical way of attaching it to the MB.
So this way the laptop doesn't turn into e-waste when a 12 year old kid codes the next website in java and uses too much RAM. Do you think this would be feasible?

That’s crazy talk!

Yup, that is just as easy as pulling out a DIMM and swapping it for a new one. That grass is totally the same colour as all other grass.

But yes, the title of the article is terribly misleading. I don't think Apple will worry too much, as the operation is terribly error prone and, unless someone starts offering upgrade services at relatively low cost, it will be noise.

The M1 being the initial iteration, one very clearly derived directly from the iPad Pro’s SoC, it’s not surprising that it’s also a PoP. I mean, in essence, the M1 Macs basically are the iPad Pro hardware architecture moved to two different form factors.

I see. That brings an interesting wrinkle where an iPad Pro could then potentially run macOS. Sure, such operation would be just a patch away, but it certainly makes you wonder.

Since they intend to roll our Apple Silicon across the Mac product line, including high-end pro workstations, they’re going to need to scale up all the hardware, and I doubt you’d even want it all tightly integrated for thermal reasons. Plus they’re going to need to break out PCIe buses and stuff for expansion, since the pro customers need things like uncompressed video capture cards.

Freudian slip?  :-DD

At any rate, I agree they can diversify and explore alternative options, but one of the most common bottlenecks for high end ARM processors is interconnections - memory controller, I/O, etc. One thing is the command line project build operation mentioned by BD139, but another are latencies and sheer volume of transfers when using high performance 3D and computing graphics. The scalability of their current architecture remains to be seen.
