1. This shouldn't be an issue. Nintendo has allowed for carts containing multiple titles for years now. Inserting the cartridge causes all the games on it to appear on the home screen.
2. The Switch is massively popular. Assuming the cartridge works and sells even somewhat well, we will 100% see games being shared in whatever format it uses. It might take awhile for the Switch's full back-catalog to be dumped and uploaded in the new format, but popular / recent titles will be circulated within a matter of days. If there's a way to convert existing XCI / NSP rips to the new format, there are plenty of individuals / groups who will race to get everything converted as quickly as possible.
3. Assuming the cart is completely transparent to the Switch, which is likely to be the case, then I see no reason why updates wouldn't download as normal. If Nintendo is able to detect the carts and ban Switches that use them, it may still be possible to access updates by rolling them into the same file as the base game and loading them from the cartridge. Personally, I think the second option is fairly likely, as it's already possible to do this with NSP rips, and it's the method that offers the most resistance to whatever countermeasures Nintendo may deploy.

This post makes me want grilled cheese, but I don't have any bread right now and all the stores are closed because Thanksgiving.

CDs have been making a slow comeback for the past year or two, and global CD sales actually went up last year for the first time in over a decade. If it's anything like the vinyl or cassette resurgence, I imagine it won't be too difficult to find places that sell CDs in a few years.

Not just technically. The killer combo of FOSS operating systems is GNU/Linux on desktop and Android OSP on mobile.
I'm curious what the person you replied to is running on their phone if it isn't Android based.

I've found that Reddit's search generally works when searching within a specific subreddit, but otherwise it's mostly useless.

I've only ever heard about it from things posed here

My dreams tend to be way more intense when I'm stoned, but I have a much harder time remembering them afterwards.

The version I've always heard isn't that the expansion pack "randomly fixed it", but rather that the issue was a memory leak that would cause the game to run out of RAM and crash after a couple hours. The extra memory of the expansion pack would just delay the crash for an additional 6-7 hours. I'm curious how true this is actually is now, as it seems like it would be easy enough to test.

Yup.

I was vaguely interested in Dark Souls for years, but every time I tried, I bounced right off it. I went through a cycle where every year or two, I would pirate one of the souls games, try it out, give up on it after an hour or so, and do it all over again the next time I was sufficiently compelled to give the series another shot. This happened until several years ago when I tried Dark Souls II, and for some reason it finally clicked. I played my pirated copy of Dark Souls II for about 10 hours, before a random crash corrupted my save file.

After that happened, I immediately bought the game on Steam and proceeded to play it for the next month and a half, until I eventually beat it. I've since purchased every souls game plus Elden Ring on Steam, and recently imported a copy of Bloodborne GOTY edition after spending $700 on an exploitable PS5, just so I could play it at 60FPS. None of these legitimate purchases would have ever happened if I hadn't been able to repeatedly pirate Dark Souls for about five years.

Which sucks, because Arkane was one of my favorite developers before the quality of their output fell off over the past five years. I loved the Dishonored games, and Prey is the single best immersive sim ever made. I was looking forward to DeathLoop, but it ended up being kinda meh, and Redfall has been so universally panned that I haven't even bothered to try it.

No, it was inaccurate, even at the time. The Famicom was built to cost and and mainly used cheap off-the-shelf components that were already obsolete when the system first released in 1983. The NES released in North America the same year as the Commodore Amiga, a system that actually was cutting edge, and represented a big leap forward in what home computers could do graphically. By the time Mega Man released, the Amiga was on it's second revision and other home computers were rapidly catching up to it's capabilities.
While Mega Man was one of the best games on the NES, it ran at the same resolution as every other game on the system, and was stuck working within the same limited color palette and low sprite limit that were more than five years behind the curve when it released.

My handheld vaporizer isn't nearly that efficient, but it is still crazy how efficient is is compared to smoking. Awhile back I was given a pickle jar full of bud, and it took my partner and I about 2 months to get through 1/5th of it. We ended up giving the rest to a friend who mainly rolls joints, and he burnt through all of it in under two weeks. I was genuinely shocked when he told me he had used it all already.

Dry vaporizing takes time to hit you (5-10 minutes)

I primarily use a vaporizer, and this isn't really true in my experience. Usually, I start feeling it within 5-20 seconds of taking the first hit, and it ramps up in intensity over the next 20 seconds to a minute. If I didn't feel anything for 5-10 minutes, I'd be concerned.

I'm pretty sure all the edutainment titles predate Charles Martinet as the voice of Mario, and I don't think Nintendo would ever make a game like that these days.

Because you're my 5 year old god daughter who always wants to play as "Uwiigi".

Do they even need to replace him though? There's a 25-year back catalog of recorded voice lines to recycle, and most of those consist of "Let's-a-go" and "Yahoooo!" I think the most complex sentace I've ever heard Mario speak in game is "Thank-a-you so much for playing my game". Combine that with AI voice recreation, and there's literally no reason to ever hire a replacement. Just cut Martinet a big-ass check for perpetual use of his voice, and they're golden.

Define "late"

Unironically, yes. Multiple studies dating back years have found a link between high intelligence and various mental health issues.
There was one particular paper I read about a decade ago, where researchers surveyed a bunch of collage students to find demographic trends based on their preferred operating system. From what I recall, the demographics of Windows users were not too far off from those of the university as whole, and Mac users were similar, aside from women being significantly over-represented. Linux users on the other hand, were almost all men, and nearly every mental health issue imaginable was over-represented by a huge margin.

I have a somewhat large share on Soulseek. It's fun to occasionally go through the chat rooms and ban all the blatant racists and homophobes.

I'm surprised that Gran Turismo was number one is 2005. I remember Star Wars Battlefront II being the hot new game everyone was playing at the time, and Star Wars being huge in general due to Episode III releasing that year. Just the fact that a PS2 exclusive driving sim, beat out a multi-platform Star Wars game that was one of the most hyped releases at the time is insane to me.
