What does it mean when the masks aren’t affective against the Delta variant of Covid? ?

So it seem that the masks are not very effective against the delta variant it’s seems to only work 30%50% of the time with the N95. Basically making the clothes mask worthless and the gators that people were wearing more dangerous.

it seems to me masks really didn’t work in the first place with the alpha variant the one that came from Europe and the delta variant is way way way less effective. So what if it turns out I right and masks are pretty much useless.

regardless if I’m wrong or not let say I’m correct in my analysis what do we do as a society.

do we:
lock down or
except that Covid is out there and go about our normal lives like we did in 2019
