Yeah, not sure if it's dishonest. By a lesser standard of sentience it certainly doesn't matter. My whole point really is that if he's going for the kind of argument I think he's going, this output doesn't matter all that much. If this line of reasoning is embraced, the same will be said about many AIs.

There's no doubt what Lambda does is insanely impressive, being able to have any conversation that lasts more than a few lines is already a huge step forward. But yes, sentience to me requires a bit more long term persistence, like learning over weeks and months, not just being able to have a 5m conversation.
