Michael Anissimov looks out at a universe devoid of intelligence other than our own. Here’s a clip, referring to Frank Tipler’s 1980 paper “Extraterrestrial intelligent beings do not exist”:
It was quite a few years ago when I looked up to the stars, with Dr. Tipler’s book in my hand, that I realized he was right – the stars are empty, ready to be harvested and spun into pure energy with the help of gravitational singularity goodness. No aliens, green bug-eyed ones or otherwise, are waiting there to be inconvenienced.
Luckily, hypertelescopes may finally put the nail in the coffin of SETI – perhaps 100 years from now. We will be able to see even the simplest of flora, if they exist in large numbers on exoplanets. (Though what we should really be looking for are Dyson spheres or disappearing stars, and as far as we can tell, there are absolutely none.) After we look at a good thousand earth-sized objects and see nothing there but vast, dead wastes, we’ll start getting used to the idea that we are truly, actually alone.
My own guess is that ETI does exist but is spectacularly rare.
