Steve Jobs was back in 1997 as a “developer advisor” on programmer productivity and his opinions on building good apps as a programmer:
The way you get programmer productivity is not by increasing the line of code per programmer per day. That doesn’t work. The way you get programmer productivity is by eliminating the line of code you have to write. The line of code that is the fastest to write that never break that doesn’t need maintenance is the line that you never have to write. The goal here is to eliminate 80% of the code that you have to write for your apps.
