I see the author is born in 1991, so they got from ~29 before the pandemic to ~33 now. This is an age where ime such changes are very probable to happen in our generations anyway when the age groups one associates oneself with are around that, pandemic or not. The author probably connected them with the pandemic because maybe there was not continuous time of them happening as it normally would, due to the lockdowns, and it would seem like one just woke up to a new reality after. But some of what the author describes (eg less spontaneity in going out) would probably have happened in some way. It seems to me that if one is in such a position, they may need to find new friends whose lifestyle align more with theirs instead of being condescending that they know what people should do better than them, or seeing the world through binaries that do not exist (introversion-extroversion is a normally distributed trait, not bimodal).
