Earlier quoted context omitted.
The computing power available today is such a double-edged sword. We can do so much more so much faster, but then we (including myself in this) waste so many cycles on abstractions and frameworks and layers of libraries to make our development jobs easier.
The tradeoff isn’t dev job easy vs better performance. The abstractions allow devs to build faster or work on things users care about instead of unobservably better performance.
It's imperceptible because the hardware has gotten so much faster. This would be like a top fuel dragster the size of a freight train.
The engine is incredibly powerful but the overall performance is hindered by the size of the overall vehicle not being optimized around it.
