Only consciousness I'm sure of is my own. Everyone else, it's a leap of faith. I have no trouble extending that leap to cover AIs.
It's not a huge leap, to me, to say "I am conscious, therefore other beings are too." I also extend this to animal and plant life (albeit the latter is very much different from animal consciousness, which includes human consciousness).
"AI" is nowhere near the level needed for true consciousness. That would be "AGI" and I believe that is still 50 years away just on raw computing power alone.

You "know" because of empathy. You're a human, you're conscious, therefore other humans are probably conscious too. The truth is for all you know they could be soulless golems, you just choose to believe otherwise. It's a spiritual belief.
Yes. Thats part of human reality. Denying it is counterproductive at best.
