The algorithm would have been created by a mathematician no matter what. Spreadsheets don't create equations to judge credit worthiness they only execute them.

The algorithm would have been created by a mathematician no matter what. Spreadsheets don't create equations to judge credit worthiness they only execute them. Because computers don't create process they just automate it. So the difference between the equations being used to calculate credit worthiness should be unchanged whether you're using a computer or a pencil and paper. The computer just does it faster. That in turn means the numbers can be tweaked no matter what. If anything, the computer makes it harder to tweak the number because a manager who oversees you only has to check the 6 numbers you put in and not spend an hour redoing your calculations by hand. The reality is mathematicians wouldn't be giving loans no matter what. Just as physicists don't run power plants they just make a procedure and pass it off to a lower paid laborer. So Joe Spreadsheet would be the one giving the loan regardless.
