Skeptics always like to toss in 'if ever' as some form of enlightenment they they are aware of some fundamental limitation of the universe only they are privy to.
Awareness of a fundamental limitation would eliminate possibilities to just {not at all}, and the phrasing would be “never”, rather than “not soon, if ever”.
I’m not quite as certain as you are, though. Just because a technology is possible does not mean it is inevitable.
Completely disagree. Intelligence is self reinforcing. The smarter we get as humans the more likely we'll create sources of intelligence.
