My own take is that although life may be relatively common, technological civilizations are vanishingly rare. Evolution is without any goals, so evolution leading to tech capable intelligence may be entirely coincidental. It only happened on earth once and only after over 4.5 billion years of evolution. And Earth has a number of 'evolution accelerators' that may be rarer than life itself. I'm thinking of our huge moon, periodic asteroid impacts and gas giant. One less or one more large asteroid impact and we wouldn't be here.
It would not surprise me if we are the only technological civilization in our galaxy.
