That’s just half the truth. He was reluctant to upgrade the instruction interface.
But the speech synthesis itself could have been 25 times better - it is nowhere near to anything that has a learning curve. And Apple has more tech that was never successfully offered - the only connection between Tim and Steven was that there was no connection
The debate over Steven's tech interface upgrade, preference or support factor is warranted without one sharing the opinion that TC is an egocentric, opportunist putz! That IMHO goes without saying. That does not mean he's not worthy of his position.... just wish he had his priorities in better order.
As for his homage/eulogy to SH I think he's being sincere. We all can agree that a great mind is no longer with us.
