Why are upper-main-sequence stars also called high-luminosity stars unlikely sites for intelligent civilizations?

Our Earth is about 4.5 billion years old. While making any hard-and-fast assertions based on a single sample is foolish, it seems likely that it took quite a while for life to develop the Earth, and a substantial LONGER time for intelligent life to develop.
(The fact that the Earth has been irregularly whacked by large objects from space hasn't helped much.)
If our single example is typical (about which we can only guess) then high-mass stars which develop and go nova or supernova in less than a couple of hundred million years may not allow enough time for life to form on any hypothetical planets around them.
However, it is possible that other forms of life might arise in vastly different environments, and might happen much more quickly. The physicist Dr. Robert Forward wrote a Science Fiction novel entitled "Dragon's Egg" concerning a race of intelligent beings who live on the surface of a neutron star.

What is the difference between intelligent guess and crude guess?
A crude guess is made with little analysis. An intelligent guess uses some information to improve the quality of the guess. The information that is used may refer directly to the whatever is being guessed or may be used to eliminate unlikely outcomes.
Why is it unlikely that aliens have visited earth?
Is it, really? I believe we know too little about aliens to assert that such a thing is unlikely: for example, what percentage of planets have life, what percentage of that is intelligent life.It seems likely that there are other planets with intelligent life. However, if they have found way around the speed limits set forth in the General Theory of Relativity and therefore are able to travel the distances involved, they would be so far ahead of us that we would be completely uninteresting to them.
Will dolphins take over the world?
It's very unlikely. Though intelligent, dolphins can't go on land, and I don't see them creating a device to get themselves there. We're safe from a dolphin apocolypse for the time being.
Could a Roman Emperor believe in Buddhism?
Yes, if he were so inclined, a Roman emperor could believe in Buddhism (or any other religion for that matter), however it would be highly unlikely. Buddhism has eastern roots, and although Rome had contact with India and China, the two civilizations were not culturally close and did not share each others belief systems.Yes, if he were so inclined, a Roman emperor could believe in Buddhism (or any other religion for that matter), however it would be highly unlikely.
