It will never be as scalable to outperform visa to serve as everyday payment solution for whole word (7.7B people).
We already did outperform VISA when we introduced the second layer solution called Lightning Network.
i understand LN fangirls mindset is like saying
'we out performed bank wire transfers of dollar by introducing visa'
but remember visa is a separate payment network than bank wire and "visa" is not "dollar"
try calling LN a multi crypto fast payment network, to actually describe what it is and does (its actually good PR for you fangirls).. pretending visa is dollar2.0 is inaccurate.. as is calling LN, bitcoin2.0
oh and LN did not out perform visa by any metric
there are only ~32 thousand users on LN
