History will always exist because I will personally keep a copy of all of it. The chain grows by 140GB/yr, and it's within my budget to buy two new 10TB hard drives every 7 years (two for redundancy).
Ah yes. In a completely "trustless" and "decentralized" environment I'm asked to trust an unknown centralized entity that they will keep all the historical data and have it open for inspection, pinky swear.
Literally in my first comment that you keep responding to with handwavy things like "surely someone somewhere will store it perhaps maybe we don't know but you just have to believe"
In other words, you need a copy of everything that's ever happened on Ethereum because it makes you personally feel uncomfortable that the internet eventually forgets things, but you want other people to host it for you for free because you don't feel like buying a new $200 hard drive every seven years to store a copy yourself?
I'm blindly guessing. You didn't actually say in your first comment why you care about having a copy of all historical data. Unless you're implying that in over a year you may need that data to personally mete out vigilante justice to the Axie hacker or something.
