...and technological advancement is likely much rarer and burns out too fast. It's unlikely we'll ever receive a signal from some advanced civilisation, and if we ever survive long enough to, chances are it's long long dead shortly (but not in cosmic terms) after the signal was sent.there is a theory that suggests that we follow the normal sequence of all civilisations, all destined to destroy their home planets and die out.
That is also one likely reason why we could not contact any extra terrestrial intelligent lifeforms.
