Which skill is more important for Physics in the modern era? From what I know, Newton (along with some other fellows) developed Calculus in order to solve problems in Physics.

At the same time, today's computers can perform calculations in seconds/ minutes that would have taken days/weeks in the past. Does this mean that programming knowledge is more useful than mathematical knowledge when it comes to Physics? VS.
