This event is surely in hype and many btc enthusiast including me are waiting for Dorsey to make self proclaimed genius know the importance of bitcoin and these memecoins he is promoting and changing his twitter profile picture for personal benefits won't work any long.
Possible scenario:
At the event Dorsey to EM : What benefits you see in these shitcoins or memecoins on top of bitcoin and how do you see development team working on them ?
EM : I am in talks with them and will make faster transaction speed and low fees so it's going to the moon
So all this is enough for coin to provide security in a complete decentralised manner?
EM : We will think (inside his mind I should not have come to this event and focus on my Tesla gigafactories only)
His reaction at the end of event will be like this :
Then he might give statement Tesla is thinking to accept btc again
