Accounting practices, professionalism, standardization, etc have obviously evolved tremendously since then, the same way any technology does as adoption increases. Math wasn't fixed between the invention of numbers and the concept of zero, but it became far more powerful when you incorporated it. Another way to think about it is with cars. Cars today bear no resemblance to what they looked like or were capable of when they were invented, but nothing around the core idea of putting an engine on wheels has changed. The airplane was different. (But so was the Segway)
