The joke may not have translated the way I wrote it; IBM makes promises about Watson's intelligence that it can't live up to, and we've had clients in the past who've come to us because we can do (some of) what Watson advertised but couldn't deliver.

The main way our system would combat bias is by shedding light on it. No human-built system could be completely impartial, but ours will say "I decided X because of A, B, C, and D", and if people decide that C is biased then that piece of knowledge can be adjusted accordingly.
