I believe that were of mayor concern last time I checked up.
How will bitcoin attract customers from traditional payment options if fees are higher?
One thing - it is not actually implemented in full and therefore can not be used in vivo.
With today's digitalization even stock trading is commonly available at $0.1 in courtage fee, is it really feasible bitcoin to use double that if broad adoption is appreciated? Or is that not a prioritized goal?
What stance does the bitcoin foundation take or whichever is the highest authority talking on behalf of the community?
From what I undertand, it's not a goal for Bitcoin Core (lead dev team for the official client). They want to make Bitcoin a "settlement layer" that serves as a foundation for other things to be built on top of. Lightning network[1] would be the layer built on top that supports microtransactions.
There are others who believe that Bitcoin should be able to scale to support microtransactions and other features itself.
There's a very large controversy in the community over this.
