Fred Wilson, Silicon valley's top venture capital union co-founder, said the top three technology companies will be Google, Facebook, and another one which is not known around the world yet according to the market capitalization by 2020.

For such a judgment, the TechCrunch founder - Michael Arrington, wondered why people can’t see a bright future of Apple?

Wilson responded that Apple is a hardware company in its bones. It will bring the challenges for its future development because of the overall bad cloud service products.

Wilson added that Twitter would also have a nice future, its market value in the industry of science and technology can rank up to the top five, six or seven, but it can't surpass Google and Facebook.

Wilson holds a critical attitude towards Apple. Last year, Wilson also pointed out that iPhone 5C which was sold with a high price made people inconceivable.
