You must be kidding. A scroll-through and peek at the contents shows that it's at best in the wrong place. Plus way too long for most readers' eyeballs to not fall out.
For text generation the result would be almost useless since most public domain works are very old. For images, you could train with video feeds maybe.
There are a lot of keyboards out there inspired by the Space Cadet. You can probably spend a while picking one out. There are even some original ones still in circulation.
Added: somewhere around here I have an old Gateway keyboard that is a knockoff of an IBM Model M, I believe. If I can find it and if you want to cover the shipping cost, I can send it to you. I expect it either has an old school IBM PC plug, or maybe PS/2, but anyway older than USB. Getting it connected to a modern computer would require an adapter that might be hard to find by now. Like the model F, it is big and heavy enough that using it portably would be impractical, but I guess practicality isn't everything.
It's sort of the other way. Buildings in the southern US before the 1960s, besides having gendered bathrooms, also had separate bathrooms for white and black people. So 4 kinds of bathrooms. The Pentagon today is apparently a bathroom user's paradise, because it was built in the 1940s with enough bathroom capacity for all its users even having the 4 kinds of bathrooms. Then after desegregation, its bathrooms got consolidated into just 2 kinds (by gender). So it now has 2x more bathroom capacity per person than newer office buildings have.
That keyboard (even the "space saving" version) is huge and weighs a ton and doesn't blend with the idea of a portable system. If you want to use it at home and it's worth the expenditure to you, then fine. If I were tight on funds and wanted to homebrew a laptop I'd probably start with a cheap keyboard, with the idea of upgrading later.
I think nowadays, laptops don't need built in keyboards for the most part. It's ok to use a completely external keyboard. I've been using a Logitech K400 (wireless keyboard with USB dongle and built in trackpad) with my laptop ever since the laptop's own keyboard broke, and it's been fine. The K400 is a fairly crappy keyboard but it's cheap, and it's one of the few that I could still find with a built in trackpad. Those were once popular but now have gotten rare. I don't know why. Depending on your power and portability requirements, you might be better off departing quite a bit from the traditional laptop form factor.
I'm not convinced at all that an ARM processor will be as FOSS-friendly as an x86. For example, I believe the Raspberry Pi still depends on binary blobs. I have no idea about RISC-V but I think the available boards cost more and have lower performance than ARM boards or maybe even x86.
I've been content to run Debian on older Thinkpads. If I were really determined I'd use Coreboot (or whatever the current ideologically correct fork is called), which does work on some Thinkpads. But I haven't bothered.
Too janky, too much JS crap on the website, appears to be closed source, no obvious self hosting option, meh. No I couldn't imagine using or recommending it. Sorry.
Craig was more like the Bond books I thought? A few of the earlier ones like On Her Majesty's Secret Service followed the books, but the rest were way out there. I don't think I've seen any of the Craig films all the way through though. I saw part of one on TV.
I mean, nobody is going to arrest you for posting it here, and I'm sure it's well intended, but it's unlikely to get any traction here.
