2. Highest resolution/bitrate/quality that was available at the time of the work's original release.
Arguably higher. For example, fans of Star Wars have scanned the original 1977 theatrical release with very high quality film scanners and created a 4K release complete with film grain and the original scenes intact which is not available through approved channels.
That's a bit of an edge case, powered by the absolute, lovely turbo-nerdery of a few dedicated souls. They are called 4K77 / 4K80 versions for people looking for them.
And actually it’s funny: self-driving cars and cryptocurrency are continuing to advance dramatically in real life but there are hardly any front page HN stories about them anymore.

AI is now a field where the claims are, in essence, that we're going to build God in 2 years. Make the whole planet unemployed. Create a permanent underclass. AI researches are being hired at $100-300m comp. I mean, it's definitely a very exciting topic and polarizes opinion. If things plateau and the claims dissappear and it becomes a more boring grind over diminishing returns and price adjustments I think we'll see the same thing, less comments over it.
