There probably aren’t aliens who are smarter than us via biological evolution. The cost of a large brain is just too high. It costs a lot in energy of course, which generally causes evolution to disfavor it. Child birth and care are extremely expensive for large brained creatures. Human babies need to be born in an extremely helpless state just to get their massive head through the canal. Then there is more than a decade of relative helplessness that the parents must put off survival tasks to handle. This article describes yet another disadvantage - accelerated cognitive decline. If there are aliens more advanced than us, I’m 100% sure they’re synthetic.
