According to Mark Cuban(who I'm pretty damn sure knows what he is talking about), it isn't remotely a bubble, because in the dot com bubble everyone was investing - regular working people quit their jobs to become day traders, you would hear people at the coffee shop talking about the prices of stocks they bought, etc. Then when the bubble burst those who hadn't got out while they could lost everything and more. Now its VCs that are throwing money at everything, and they've got more than they know what to do with, and will be just fine if companies they invest in fail.
