Since all life evolves from less complex life, I'm of the opinion that for a species to become technological, it must have attributes like we have.
We use 2 legs to be mobile (minimum requirement)
2 eyes for 3D (minimum requirement)
2 hands for doing the technical stuff
we have hardly any redundancy built into us (minimum requirement of organs)
Isn't this how a land animal would evolve naturally? Using the bare minimum needed to survive.
I think of that a different way: It's most efficient. Additional limbs and redundant organs are extra weight. Besides having to expend extra energy to carry them around, the body must expend energy and other resources just maintain them. If it's not something you regularly use, it's more of a liability because of what it costs.
Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
