Not sure on the technical details of exactly how long they last, but I've heard similar things several times before.
Always depressing to be reminded of this. Haven't had many fail, but honestly haven't tried a lot of my 3DS/Vita games in a while, so who knows.
If nothing else tho, it's nice to have an excuse to revisit some things. Once you boot it up, you might find yourself enjoying the reminiscing. :)
Honestly, with the fact the 3DS servers are gone, don't even bother with a second one, just hack your main one.
There are 3rd party game servers still running, which means you can go back to playing games online, especially with a hacked 3DS.
There are even tools to transfer files to/from your computer wirelessly, which is great for not needing to shuffle SD cards constantly.
I wonder if they ever got A Link Between Worlds working. I played that on my 3DS and wanted to emulate it for higher resolution but, like you said, it ran like doodoo compared to other 3DS games.
