If we ever encounter aliens, they will resemble AI and not little green martians

My colleagues and I look for extraterrestrial life, including intelligent beings – or in the vernacular, aliens. It's exciting times for people like me, because extra-terrestrial life is being widely discussed now in the lead-up to the Pentagon's highly anticipated report on so-called unexplained aerial phenomena. Yet, I should say straight away that, I am not expecting any big revelations out of the report. I think it's overwhelmingly likely that aliens are present in our galaxy. But I don't believe they're hanging out in our airspace.
