Motivated by recent developments impacting our view of Fermi's paradox (absence of extraterrestrials and their manifestations from our past light
cone), we suggest a reassessment of the problem itself, as well as of strategies employed by SETI projects so far.
Quite an assumption there- 'absence of extraterrestrials and their manifestations from our past light cone'. I don't think anyone can claim to have
searched our entire past light cone. Our legendary history is replete with posssible visitations/interventions.
If ET does not want to be seen, they will not be seen. And, thinking from their point of view, I can think of a thousand reasons to not want to be
seen. Being seen might attract juvenile predatory species- like, say, humans.
I would use tightbeam frequency-shift encoded burst mode communications, if I were Galactic Emperor...
Great post, rancid1
