I don't think anyone would argue against there being an adoption curve for a new technology and therefore you can plot performance or number of users on a Y axis. You could have done the same with TCP/IP or other protocol technologies that are similar in idea to the btc blockchain. I think the question is will the btc blockchain be a long term winner, industry standard, etc, or will something better come out tomorrow. The current price could easily be a bubble. I'm not saying it is, but it could be and BTC may turn it to be more like the laser disk that the vcr.
