I have been mulling this over for decades.<br>
<br>
We look out into the Universe and don't (so far) see or hear any<br>
evidence of technophilic civilization.<br>
<br>
I see only two possibilities:<br>
<br>
1) Technophilics are so rare that there are no others in our light cone.<br>
<br>
2) Or if they are relatively common something wipes them *all* out,<br>
or, if not wiped out, they don't do anything which indicates their<br>
presence.<br>
