Maybe, but more likely no mammal or any other animal would have developed
intelligence if the asteroid hadn't killed those specific species; a
surviving species would have outcompeted one of our tree living ancestors
and today nobody would
be very smart.
Intelligence probably needs a very unusual set of developments to happen.
Life has been around for nearly 4 billion years and there have been
hundreds of millions of species, but only one has had enough intelligence
to develop technology, and that only happened about ten thousand years ago.
That tells me that the Evolution of intelligence is far from inevitable,
I think we just got lucky.
