Anecdotal over-investment on the part of three VC companies != a bubble.
A bubble is a stock market bubble based on massive, irrational over-investment on the part of VCs and stock market investors which, after implosion, will hurt the US and world economy.
"Hey, those VCs are making some stupid investments" does not translate into an economic bubble. VCs frequently make stupid investments, because they're human and they're in the business of taking risks.
Please, I urge you to read a history of the actual stock market dot-com bubble of the late '90s so you understand the word "bubble" in context.
