In response to Elon Musk's query on social platform X about whether he is too rebellious, co-founder of Ethereum Vitalik suggested: 'There is virtue in the challenges, but focusing on creating appealing and respectable alternatives holds equal importance. I believe directing more effort towards this would help you achieve your goals for humanity and happiness. After all, I am just an observer.' Vitalik's advice aims to guide Musk to concentrate on developing more valuable innovations, promoting the development and progress of human society.
