### There is insufficient data on that. Knowing a census but in the absence
of knowledge about the rate of formation of life, you cannot estimate the
rate of intelligent life disappearance.

### You should not let emotional considerations influence your estimates of

### Indeed, if for some reason you assume lots of ETs are born, then given
visible evidence, they die soon or stay alive invisible, and I would agree
that staying invisible may be more aspirational than dying.

But why assume that lots of ETs are born?  There is so far no strong
evidence to that effect.
