Which level in corporate hierarchy will most IT / Software engineers retire?

Software and IT revolution started in India almost 1.5 decades ago and we're yet to see a bunch of engineers who joined the industry as 'freshers' and have reached retirement age. There are people who've been associated with computers for much longer (several decades); but I'm mostly talking about people who joined Wipro / TCS / Infosys as 'fresh graduates' in the industry - and are now at mid-management positions.

Of course, not everyone would end up becoming a CxO; but what level in the corporate hierarchy do you plan to retire at - by age, choice or by hmm, force?
