This design decision reflects the computer scientist’s perspective that ‘history’ is less important than the price of its storage.

Funny, I don't recall that sentiment from any of my CSCI classes. Seems to me like this methodology has more to do with the fact that a 5 MB hard disk (for example) used to be the size of a washing machine than it does with whether or not the person writing the DBMS was a computer scientist.
