hopefully that would be the case...or perhaps my world view is a bit too pessimistic, but I feel that these days there are just too many different goals -- and many of them are mutually exclusive -- are amalgamated in academia... I have seen quite a few cases where people with PhD degree in physics or mathematics went to Wall Street and became traders there and totally gave up their original pursuit of physics or mathematics... also it is not a small number of people who would choose to pursue an academic career not because their research interests them but because it brings them fame and admiration, as well as stability in life -- as once they obtain their tenure, they would go start companies and pursue profits, instead of discovery... I am not saying that there are not many people still hold their academic ideals pure and high...It is just that in this era when academic positions are highly respected, admired and well-paid, it might give people the incentive to pursue such a career not for its original purpose but for something else....And one of the very reasons why these days academic positions are highly respected, admired and well-paid was because those scientific and engineering giants in those old days had made really prominent and conspicuous contributions that made this world a significantly better place than it was a century ago -- and if we trace further to the reason why they chose science and engineering as their career in the first place and then made great contributions afterwards, it seems that in many cases it was not because science and engineering could bring them material profits, but rather they were genuinely interested and intrigued; and it was extremely fun to them... But of course, it is a very difficult to say whether there is such a general decline in our pursuit for knowledge in general (such measurement is hard!)...not to mention the complexity in the essence behind some of the declining factors and drives... Nevertheless, I wish that at the time when I am old and feeble, as I look back at those days in our time, I could say to myself, just as Odysseus might have said to himself, that I have lived in an age of many great ideals and many great heroes...Yet still, I feel that we should be warned that after the heroic Mycenaean period[1] ended, what immediately followed was several hundreds of years of darkness in the ancient Greek civilization[2]...
