Disruptive technologies will have disadvantages (assuming it's a disruption from the bottom) but they need to have practical advantages too. "Living the future now" is cool -- I buy tech based on that -- but it's not a practical advantage. Compare this to the low cost hard drives of the 80s. I think Tesla is actually trying to be disruptive from above, which is a perfectly reasonable strategy. Unfortunately, to be disruptive from above you have to be better than the existing tech, because you have to justify the premium price. I may be nitpicking here, however. I completely agree with your point on how to take and evaluate criticism.
