From a pure layman's perspective: if you believe in evolution, then what separates us from a reptile (as mentioned in the post) is almost certainly something we can figure out and replicate. There is nothing "special" there.
So if you believe computers today already have the "intelligence" of a reptile, or a toddler (i.e., ability to play pong), or something along those lines, it's only a matter of time before a computer has the intelligence of a full-blown adult human (and soon thereafter much more).
Our level of intelligence/awareness seems magical only because we haven't fully understood it yet. That will change.
