We are now at the point when we will find out which of the changes to behavior (financial and otherwise) that came about with the onset of the covid-19 pandemic are going to be lasting, and which are not. I do not claim to be able to predict which ones (if any) will last, but I can confidently say that Robinhood is not the only one to have been surprised by changes which they thought would "stick", going back to pre-covid norms.
