Hmm, is that true? Just from a numbers perspective, it seems like there would be far more experienced software engineers than brand new ones.
The answer to the original question depends on the rate of growth, how you define more experienced, etc. So it's not obviously true or false.
Hardly. At best it can be described by a second-order differential equation. An experienced engineer would avoid the inappropriate term 'exponential' to describe the phenomenon. The rest is true.
