Why is an M2 Pro or Max preferable to an M1 Pro or Max? Is 8 GB of memory sufficient? Can I extend the internal SSD with an external drive? Can I buy and upgrade?

In a VM hosted on an M4, upgrading 14.7.5 to 15.4.1 took an 8.7 GB download and worked. From 15.1 to 15.4.1 took over 15 GB and failed with a kernel panic.
Intel Macs tell you why they last shut down, in the ‘shutdown cause code’ written to the log by their System Management Controller. What do Apple silicon Macs do?

Is it possible to update a VM running macOS Sequoia to version 15.4? Three attempts, three failures. And why are all those file creation dates wrong?
Systematic and thorough account of the structure and function of bootable external disks and dual-boot systems from High Sierra to Sequoia, and how to diagnose their problems.
Can you install macOS Sonoma on an external SSD for an Apple silicon Mac running Sequoia 15.3.2? So far this has defeated two of us on many attempts. With useful tips that should have brought success.
You could save hundreds of $/€/£ buying a Mac with a smaller internal SSD. Is that a good economy, or will you come to regret it? Here are the pros and cons.
How Apple’s new CPU cores can guess which code to run, and which data to load from memory. How those speculative techniques can be exploited, and should we be worried?
Working with external bootable disks: how to create and add them, ownership and LocalPolicy, how that can be changed, and what happens with errors and failure.
