There could also be life in the clouds of Jupiter-like planets or in the clouds of planets like Venus...

Earth wouldn't have qualified as a 'Type 1' planet back in the time of the dinosaurs due to low oxygen levels (10 to 18%) compared to around 21% today. The air was breathable back then but I wouldn't say it was conductive to a normal life expectancy.

By the strict 'Type 1' definition I too would be surprised to find any truly habitable planets.

OTOH, planets that could support earth like life (i.e. carbon/water based) are probably plentiful. With Earth as an example, where life is even remotely possible it finds away to exist and I see no reason why that would be any different on other worlds. And if life exists then the potential for intelligent life exists.

I believe that they are plentiful in the Universe. But per Galaxy--maybe only a very few. As we develop the means to look out to say 1000 light years we can test this. If we can measure things like atmosphere composition, ground temperature, orbit eccentricity, magnetic field, ozone presence, water and land mixture, stable spin and so on then we will know more.

Assuming that we are doing a proper job of listening via SETI--we should have heard anyone out to maybe 100 light years and more by now. Thus we may conclude that if there are "Habitable" planets out at these distances, then the inhabitants have not progressed to the point of having developed electronics a few hundred years ago.

The discovery of a seventh planet around the dwarf star KIC 11442793 could be a record, according to two separate teams of researchers.

The system bears some similarities to our own, but all seven planets orbit much closer to their host star, which lies some 2,500 light-years from Earth.

How about this as an idea? Send out a probe in the most likely direction for finding a planet that could support life with as many sensors and instruments as possible that could detect "life signs". On the way out of our solar system aim it back toward earth periodically and find out how far out it can detect the evidence of life here. If it can't find life here then it isn't going to be likely that we can detect life, intelligent or not, elsewhere. If it does continue to find evidence of life here then we will begin to have a gauge of how far out our instruments can find life elsewhere.

Astronomers believe that the universe is expanding - that all points in the universe are getting farther apart all the time. If that is the case, any intelligent being would be gone.

Depends on how far away the intelligent being is. If in our general neighbourhood (say within 1000 LY) then the effects of universal expansion would require billions, or maybe even trillions, of years to become evident.

Maybe intelligent life got swolled up by black holes. Maybe Not. But I love the whatifiness of the question. I hope extraterrestrial life exists. Right now it's not looking good.

I agree completely. And the time it takes to evolve into an intelligent species is a bagatelle in astronomical terms...

This report highlights how much they really don't know about these exo-planets.

judge for yourself..

An alien planet climate analysis cuts nearly in half the estimated number of habitable planets in our galaxy, scientists reported on Wednesday.

Then these are not "Earth-like" and wouldn't be unless they had many more characteristics that would make intelligent life possible.

Write down these requirements and you will have a dozen or more items that must be in a narrow parametric range.

When we start verifying that we have found planets that meet all or most of these essentials then we would have an idea of how many or how few of them there really are. All the current hype about "Earth-like" planets is pure fakery and does a disservice to the idea of SETI ; reducing it to Al Gore style pseudo-science.
