Sales of development boards will continue to anyone who wants to buy, including lay people. No one is going to be prevented from "building their own PC". A majority of "nerds" in recent times have had a proclivity to take jobs with companies that seek to "control basic access to computing." I am skeptical that they are seriously trying to convince or train "lay people" to avoid their employers. More like the other way around. If these "business models" fail, nerds lose their jobs.
M1 devices actually have quite an interesting boot security model, so you can install a custom kernel and OS and boot it, without compromising the security of the platform for normal users that have never heard of an operating system.
While a dev board would be cool, a Mac mini with the hardware UART enabled over a USB C cable is getting pretty close!
Trade offs like these arguably could help to keep general purpose computing alive, as they show it is possible to deliver a secure device to customers that can be used however you like, running whatever software you like, without iOS style "no choice available".
M1 laptops are general purpose computers already. You can also install an open OS.
Dev boards aren't necessary when an entire functioning laptop only costs $999. An M1 dev board be would way, way more expensive than that and far less functional.
Assuming this comment is from a "nerd", this illustrates exactly the point I am making. Trying to "convince or train lay people" to admire companies that allgegedly seek to control "basic access to computing". Apple computers are pre-built, they are not DIY PCs.
