The U.S. Constitution is like a legacy piece of software written by hand and published in 1787.
The Bill of Rights was the first patch deployed in 1791 with an Overwhelmingly Positive reception.
Future releases came in the form of Constitutional Amendments with Mostly Positive reviews (although certain groups of people did attempt to review bomb).
The Constitution is like x86 assembly and the Bill of Rights like C. People talk shit about both and say how both are obsolete, yet the modern computing world is built on top of these, or on top of successors to these.
