It happens all the time to people asking me for help with their computers. They are a lot more annoyed by this than me.

That's just normal Vorführeffektsgewöhnungsgelassenheit, i.e. you being chill about it because you're already used to the Vorführeffekt.

I did a google search for that long word, and it shows how fast google's index updates.

Are those fantastically long German composite words easy to read for native speakers or is part of the pleasure having to stop and squint?

I'd guess it's similar to using a lot of English words to make compound nouns, except it is slightly worse to read, so if the word is new you'd usually slow down a bit to properly parse it.

On the upside, you don't have to guess where the compound noun ends end the rest of the sentence starts, which can also cost time or cost confusion.

It's not a big deal if you know each individual word but if you don't then it's hell.

i learned a bunch of German years ago, and while i don't really know what the particular components mean, it's pretty easy for me to decompose the word into parts. do you see a "ge-" or a "be-"? its probably the beginning of a verb; an "-ung" or "-eit" are usually noun endings; etc. and this happens pretty much subconsciously
