In Silicon Valley, you can't escape bubble talk.
On one side of the ring, Benchmark investor Bill Gurley, who was an investor during the dot-com bubble, has been sounding the alarm that companies are overvalued.
In a few years, Gurley has predicted that we'll have a lot of dead unicorns on our hands. "Unicorn" is the current Silicon Valley term for a startup valued at more than $1 billion.
On the other side is Netscape founder Marc Andreessen, who cofounded his venture firm, Andreessen Horowitz, in 2009, right after the bursting of the debt bubble sent the economy into a tailspin.
In an appearance at the Fortune Global Forum, Andreessen reiterated that tech is not in a bubble. Rather, these valuations are still startlingly low for the potential of some of these companies.
