Kinda-sorta the premise of the anime Frieren.

There's a series of books called The Legend of Drizzt last time I checked (it's changed over the years, and the first book wasn't even supposed to be about him lmao) and in one of the books, our main character believes he has lost all his friends (not a spoiler, we already know who is okay and who isn't when he thinks this) and so he goes off alone into the mountains to kill orcs and goblins and shit until he maybe dies. A couple of elves way older than him meet him at one point, and since this is really the first time he's spent with elves long term since he left his underground homeland decades before, he doesn't really know "how to be an elf".

This is basically their philosophy.

Elves can live over a thousand years (one dark elf we know of is blessed by their evil deity and is over 5,000), but dwarves only about 2-400 years (I think?) and half lings about 100-150ish, humans standard 80.

Since you will lose 10 sets of "lifelong friends" at least, if they're human, many elves choose to stick with other elves.

But those that mingle, tend to segment their lives into smaller chunks.

Don't try to live your life all thousand years in one go, you will lose so much by doing so.

But if you think of your life as more "this is me now, I am very different from the person who wore this outfit 5 years ago, and this is who I will be for the next 100 years" then it becomes more manageable.

You never forget the friends and family you made in an old life, but you cannot carry your grief over losing them for the rest of your life.

Those that do end up sticking to their own kind, because it's less painful. (and also superiority complexes)

I had a character who's backstory wasn't too far off from that. The career changes weren't entirely voluntary, though, and usually were because he had suddenly lost all his money and needed to go adventuring again to rebuild his wealth. By the time the campaign was set, he was close to a millennium old, borderline senile, and making some very outrageous claims about things he had supposedly done in the past, like getting into a bar fight with Selune during the Time of Troubles or having once dated Lolth.

This also somewhat appears in the Orconomics book series (very enjoyable fantasy satire with some heart to it), where the elves in that universe are virtually immortal and don't die by aging. Instead they just slowly forget their previous lives if they live that long.

One of the main characters is an Elf who used to be an adventurer of great renown, but is a bit washed up and is constantly comparing themselves with the legends of what they used to be. Also applies that if you were an Elven prince or princess, eventually you age out and get moved lower socially to any newer born royalty.

Like, you were a wizard 100 years ago, but then spells were super different and way less powerful, so now you get to relearn the newer better spells and casting techniques.

That's an interesting (and very Frieren-esque) bit of world building. But it does run contrary to the generic D&D settings/multi-verse, where the same set of spells have existed for centuries and across a multitude of worlds.

"When I was your age, you needed to know 9th level spells to cast fireball" is a cute crotchety one-liner. But it's not going to make any sense when you find a 2,000 year old spellbook with Fireball at the appropriate 3rd level slot. The DM would have to do a whole mess of retconning of an existing setting / pre-written material to make it work.

I imagine it’d be like learning to programming 50 years ago and then starting again now

As someone who did learn programming roughly 40 years ago, there are definitely differences. But an if-statement is still and if-statement and a function is still a function. The libraries and syntax can change, but the basic commands are still fundamentally the same.

I would note that modern programming-as-analog-to-magic would be more akin to everyone having a magic wand in their back pocket to do a set assortment of 3rd level spells per day which they don't even really need to think about other than the command word. Meanwhile, you've got this ancient elf flipping through a spellbook and spending an hour every morning re-memorizing a boutique list of spells nobody has thought to make a wand for in half a century.

Also a very interesting spin on a D&D-esque setting. But hugely divergent from printed materials.

In D&D, elves don't typically get several thousand years old.
