Masking isn’t over, any more than wearing condoms was over after the main surge of the AIDS epidemic. In both cases, a lot of people were glad to give up using the protection when they had a chance, but the overall societal awareness of the potential benefits of that protection is here to stay.
People will be making their individual choices about whether/when to mask (assuming we don’t have more pandemic waves leading to mask mandates again), just as people make individual choices about whether/when to use condoms. But now most people (except the ignorant who turned anti-masking into a defiant ideological cause) understand that even imperfect protection can be better than no protection.
