The crow experiment as an analogy is so wrong I don't even want to read the rest of the article. It's a misunderstanding of statistics. We have one data point.

The crow experiment as an analogy is so wrong I don't even want to read the rest of the article. It's a misunderstanding of statistics. We have one data point. To use that analogy, it's as if we performed one experiment with one crow once and are trying to deduce the difficulty. I read a study on HN a couple weeks ago that talked about likelihood of self replicating protein strings forming randomly, and the summary is that it is unlikely for abiogenesis to happen randomly within a volume the size of the observable universe more than once. Now, there could be panspermia, there could be something non random about the process, there could be other types of intelligence, but until you show me an ongoing alien biosphere process I'm convinced it isn't common, and I don't believe we will find intelligent life anywhere we look.
