Comparing Apples and Mangoes

On 5th OCt 2011 the Co-Founder and CEO of Apple Inc. died becasue of Pancreatic cancer.
After a few days, on Oct 12, 2011 the creator of C programming language and Co-inventor of Unix operating system died at the age of 70.
     People say Steve Jobs's death tops the news agenda and when Dennis Richtie died, nobody except only a few geeks notices. But that doesn't mean that Sir Dennis Ritchie has not done anything or he was not as great as Steve Jobs. So this speculation is completely ridiculous.
As a cricket fan I will see this comparison as comparing Sachin Tendulkar to Anil Kumble, which is totally rubbish. Dennis Ritchie was great, there is no doubt about that. He invented C language, unix OS, without this no other OS could evolved. But that doesn't mean that Steve Jobs's vision, marketing priciples are meaningless.
The fact that very less people (which is not the actual case though) noticed Dennis Ritchie's death becasue he was not a person who always be in the limelight like Jobs. Sachin is famous in cricketing world becasue in this world the batsmen always take the glory, unlike bowlers. That doesn't mean that Kumble was not a good cricketor.
The only point I want to raise is a person's credibility doesn't depend upon how famous he is in public but depends upon what work he has done. And people do different kinds of work which can't be and should be compared. That's all.
