Opinion? Dijkstra is an asshole, a very smart one, but an asshole nevertheless. And I doubt that had he lived to see Cloud Computing and the shift to Mobile Devices he would think differently.
Why do I think so? The man was gifted in applied mathematics, no doubt about that, and the vast majority of his rants are reasonable. However, he seemed to have a very poor opinion of people who have to deal with the practical implementation of Computer Science: IT. He complained quite loudly because (apparently and particularly in the US) people tended to say "Computer Science" when they meant IT. Hell, I don't know where he got that from. Maybe it was like that in the 50s, even the 60s, but by the time I went to school it was quite clear that Computer Science and IT are two different animals altogether. In any case, from what I have read about him, he seldom bothered to actually use the tools of the trade. Up till ten years before he died, he didn't use any kind of computers, only then and after being prodded he actually used a Mac for email and to surf the web.
So basically I don't like him because from what I have read about him, people like me would be dirt to him. And besides, the asshole liked to lecture, if I am going to get lectured I would expect to get it from someone who at least has some practical experience, like Donald Knuth for example.
As for Cobol, meh, saw it in college (I didn't go study Computer Science, because that would mean that the only job I'd get here would be writing code, at best, and in those days that meant spending my day writing reports in Cobol or RPG
) as an elective because I was curious. Never liked it.
And now, just to piss squid off, I give you
Larry Wall talking about the 5 programming languages everyone should know why should it piss squid off? the line about Java being "the modern day Cobol" should do it
