To answer your question: MP3 is derived from Mpeg-1 video. Which is roughly VHS quality. AAC+ is derived from Mpeg-4, capable of compressing 1080p Hi-Def video to the same filesize as, or smaller than DVD/Mpeg-2 video. And it still looks much better than DVD video. In terms of technical advancement, AAC+ is in fact far more advanced than MP3. Would you prefer I spelled it out the way I just did, or would you rather read vernacular summarizing it's far more advanced? And BTW "light years ahead" does in fact refer to distance traveled, not time elapsed. The rate of technological advancement is exponential, making it effectively incalculable purely on a time scale.
As for processor speed, the difference between a Core 2 Duo, and 11 Generation i7 is in a completely different universe from the difference between the 8088 of the original IBM PC, and the 80386DX33 when Microsoft Windows became a thing. "Magnitude" would itself be woefully inadequate describing the difference between just those 2 scales. Never mind comparing the actual speeds.
Far more advanced is more accurate, although in my user experience that is not the case. And of course we - actually you, although I omitted your name from my original post - were comparing
audio in the thread that I referenced.
I know what light years means. Magnitudes can involve any type of measurement, for example compression ratios (if one were 100 times more efficient than the other). But what in the world does light years (about 6 trillion miles multiplied by the number of years) have to do with compression algorithms?
Couch is is correct that hyperbole has a place in communication - I noted an instance where I used it.
But for the most part, it is better used in communicating subjective feelings, responses, etc.
Edit - do you consider lossless formats light years better than lossy formats? And what about hi-res? Now we’re getting into some serious numbers!
Edit - I probably should have used orders of magnitude instead of simply magnitudes.
