Gosh....Prof. Gupta, I pity the students who get taught by you and shudder to think that somebody like you has become Prof. with such a narrow view of thinking. I can see the "Grapes of Sour" tone from your mail. Probably there are thousands of your students who became the so called 'coolies' earning 10 times what you are earning. Well...firstly its all market dynamics and is the question of supply and demand. If you have more demand and less supply,naturally the price goes up and which here means you are in 'demand'. Its natural when the 'demand' goes down you loose out. Looking in that sense, most of the guys who worked on Y2K conversion in 1997-2000 time frame (during which time there was discussion that these guys will become jobless after Y2K demand goes down)should have lost out and gone home. But lets agree. You gotta have better grey matter in your head if you need to be a 'coder' and most of these guys adapted and trained on another software or platform and are continuing to thrive even today but those who couldn't perished which is true as in any field. So prof. Gupta, don't keep predicting dooms day and start thinking of your future when e-class or e-teaching becomes the order of the day. Try to learn some computer and look at redeeming yourself rather than crying foul about somebody who is doing better by sheer hardwork, smartness and entreprunership.
