If talking about relativity, the distance to destination is further compressed only for your perspective, not the train's, and not the earth's. The amount compressed is imperceptible.
I spent 20 minutes (I timed it) on the phone diagnosing a tech support issue and instructing the user on how to fix it. It took about 10 seconds for me to realise that number lock was turned off.
The rest of the 20 minutes was trying to get the user to find and press "Num lock" on the keyboard.
About 10 minutes in, they actually found and pressed it. Apon noticing that nothing had appeared on the screen, they tried pressing it again, then announced it didn't work.
Somehow, just getting them to press the button one more time was not simple, as they now had to begin their logical left-to-right scan of the keyboard again to find this mysterious new "Num lock" button they'd never heard of before.
This person (on another call) would say the name of each key as they pressed it. They would say "Caps lock, A, Caps lock, Enter" when typing a single "A" on a line, but didn't know what "Caps lock" was and couldn't find it on the keyboard when asked to press it immediately after having said and pressed it.
It's not as good as Google from 20 years ago, but much better than Google today.
I didn't choose it for the privacy, I chose it because I wanted to actually get results for my searches.
Google gets me answers about 20% of the time,Kagi about 50%,and (generic - not Kagi) AI about 80% of the time.
The problem with AI as search is that the other 20% is when it will confidently give me wrong answers and waste hours of my time, so I guess Kagi is still useful to me.
