They mean not bitcoin but crypto made by the government. I think crypto made by big companies will not even be able to compete in the market, let alone replace bitcoin as the foundation of crypto money and the global currency of the future.
It takes a lot of fans to become a global currency as well as a truly sophisticated technology, lots of altcoins are popping up but only bitcoins can survive and dominate the market. And Satosi's dream of making bitcoin a global payment tool is not impossible because there are now many places in different countries willing to accept bitcoin as a means of payment.
