Amazon founder Jeff Bezos has questioned whether Elon Musk's deal to buy Twitter will give China "a bit of leverage" over the platform.

It made me very sad to read this bitter remark from the mouth of Bezos, whose achievements I love and appreciate so much.

It seems such a pity that these two brilliant and hugely successful entrepreneurs are sniping at each other instead of working together for a better world(s) and even bigger successes for both.

Jeff Bezos taught me in 1996 that 1+1=3.

I think it’s time for me to draw the attention of my Cadabra superman to the fact that $100 billion + $100 billion is easily $500 billion!
