I suppose you think you won the other time?
It wouldn't surprise me if you did.
Yes, of course I do. When the other guy stops with solid, objective arguments and starts with petty insults, you know you have won.

Exactly. What should I do instead, hug him for having such opinion? Say that the world would be a much better place if everyone acted like that?
It would indeed be a better place if everyone acted like that. What's your point?
Unfortunately i must label myself as a traditionalist in the case that I'd like us to remain imperfect bipeds for quite some time.
Sure you would, as would almost everyone else in the world up to the time that it actually occurs. The rule of resistance to change is a major determinant of the human's likes and dislikes.

If you're going to go the MO route you can get onto all kinds of fantastical (and theoretical) life-forms - including ones that aren't matter-based at all or reside outside our entropic, decaying universe.
Possibly, yes, which would be nice.
And I doubt that the growing mega-organism would be able to think as well, at least not to start with.
It would start at the highest level of human thought, and would progress on from there. It would still always be some steps ahead of the individual human.
If it was designed, it would not be more complex than us (most likely due to our imperfect thought processes or more likely our own hubris at being the most intelligent known life form) and if it came from elsewhere it would probably some exotic weapon.
Well, yes, it would, because we would be its constituent parts. But it does not need to be complex to be effective at its task.
