I agree with QuarterPastTired. Will there ever be an AI who thinks, "Yeah, I've done enough here and feel ready to let someone else take over"? If the answer is no, maybe that explains my collection of volumetric pipets (replaced by Eppendorf pipets) and mechanical analytical balances (replaced by electronic analytical balances). Btw, I am always appreciative and acknowledge Siri and Alexa when receiving help, just in case! Love the game, Alan. Gave me a new lease on death.
