I don't think they see Bitcoin as a new currency but what they might be referring in this photo is not about the evolution of money since trading is not here but the evolution of payment system that starts using the common ones, paying money then it evolved on using cards and now which we can use mobile phone applications and obviously Bitcoin.
I agree. The image does not suggest that Bitcoin will be considered to be a legit currency but just the latest form of payment in the monetary evolution. This only shows how dynamic the monetary/payment system is and that man can come up with ways to further enhance or innovate whatever technology that is existing today. So we shouldn't be too expectant on this misconception because there are just too many legalities along the way for BTC to be even considered as a currency.
