This is true, and so far Elon is doing exactly the thing everyone says you can’t do with a social network. If he succeeds, it will completely change the space. Also interesting change of strategy during an economic downturn.
But I do think one difference at least from where I’m sitting, is usually the response is, that’s crazy, but if it works you’ll be rich!
I’m not even really clear on what the “if it works” is in this situation, I guess if he proves that people are willing to pay $8 per month for a social network?
If you dig significantly you might find that they're not as impulsive as they seem, that the person was actually considering many aspects but playing their cards close until cut-off time.
