Yeah, Octorox, I’m with you. I admit that it would help continuity, but isn’t something I want to do. So I won’t! The current Hal9000 saga excuse is that Obi-Wan just doesn’t regard droids as anything special.
I do wonder if that was Lucas’ intent behind lines like “if droids could think” and “flying is for droids” in AOTC, to sort of account for his lack of recognition or care about R2 and 3PO showing up in ANH. That’s my read of it, anyway, even if it seems to have fallen by the wayside along with other things by the time of ROTS.
