Is‘t this a bit like having a shovel and imagining that in the future, there
will be truly *huge* shovels around? Not being able to imagine excavators?

The first thing such intelligence will do is taking steps towards discarding
vulnerable and evanescent biology.

I'm a complete amateur/layman in this field, but I believe neurologists will
tell you that the relationship between brainsize/intelligence isn't linear
or absolute. AFAIK even the human brain is full of "dead meat" which has
nothing to do with our intelligence/sentience pér se.

I have this awful huch you're posting this from alt.paranet.ufo, and not
bionet.neuroscienece. You're currently sunk to your eyebrows in ironic

...still sinking (anthromorphism alert!).

We don't even know what the basic premises for us resulting in our current
form/structure are, do we? And anyway your hypothetical ET's should be able
to brief us on these issues (sic.)

What observed extraterrestrial beings? Hast documentation?

One could imagine all sorts of things. It's a basic human trait of mixed
blessings. Doesn't equal the results automatically being worth pursuing
intellectually. Read http://world.std.com/~mmcirvin/vitrifax.html .
