Also, A. didn't know about Tesla, which made me realize several things quite quickly. First, explaining that Tesla was an electric sports car was completely irrelevant to him. Elon Musk didn't mean anything to him. And PayPal as an explanation for Elon Musk wasn't a very powerful explanation of any of this. R. didn't know about Musk, but _did_ remember the This American Life about the auto factory in Fremont that used to be a joint venture between Toyota (?) and GM, that was now (?) a Tesla factory.
So. Apparently, billionaires -- mostly tech billionaires, but billionaires in general -- are the only celebrities that I consistently keep track of (wow, does this say truly shitty things about my character). R. will remember anything that involves a factory. And sensible, decent human beings remain fully oblivious to all of the status implications -- whatever they might or might not be -- of fully electric sports cars.
