Earlier quoted context omitted.
I mostly agree with you, but with one exception: I'm a bit of a history buff, and I'm not altogether looking forward to a future where all of the history texts are alterable, and nobody owns previous copies.
I wonder if this will increase the number of people that sha1 the books to see if it has been tampered. maybe have a distributed system that votes for the correct hash. Or you could have a canonical repository like the library of congress.
Fixed that for you.
