I dont think poignant is the right word. Also, he is just calling attention to his blog post from 2014 so I don't think his tweet is changing anything since 2014. I'd argue there is a marketing/word of mouth angle on this that creates value for the 'Elon's trying to change the world' narrative that attracts a lot of fart-smelling rich people
