Well that's what Satoshi's vision was, that bitcoin to be used as a micro-payment scheme, sadly though, it has become just a store of wealth or as a form of investment and currently the whole scaling issue is still up in the air (although fees drop signficantly and the network spammer has stopped).

Maybe in LN would have been implemented, and it brings fees and network congestion to a minimum, then maybe we can see bitcoin being used as mode of payment in the future.
