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.
