You can do all that and more with an off-the-shelf mini PC running Linux. No need to reinvent a general purpose computer from a router. The chain of trust thing is above my paygrade, but I bet something like that exists.

Not as tough as it seems. People routinely memorize much more in shorter periods. Try learning the complete Kanji (Asian Pictograms) or heiroglyphics. It’s not inconceivable to memorize 10,000 random words. Think of how many songs you can recite the lyrics to. I learned Billy Joel’s, “We Didn’t Start the Fire” in a day. That’s pretty much what this challenge is about - a random list of words.

Looking for an explanation, yes? It’s a linguistic convention, totally. I mean, you know, we add a lot of unnecessary words, like, serious. It’s superfluous verbage. Look, I know it seems to be a recent thing, but it’s, like, been going on for a long time, right?
