I actually do mostly agree on both points.

While i do support transhumanism. i can see the negative side of any implants coming from Elon(or any current techbros), security, compatibility, long term support, minimal medical testing.
The hope is that eventually replacement body parts coming from medical field with rigours safety features and testing become widely available. That will likely take decades or even lifetimes and i might not even see becoming a half mechanical cyborg during my lifetime.

Cooking is most definitely useful skill, no argument about that and it does play into efficiency by being cheaper (per meal basis) and it is easier to cook up a balanced meal from raw ingredients instead of trying to find a good ready made meal from the store. In addition the health aspect as well, a somewhat balanced meal cooked out of raw ingredients is likely going to be better for the body than ready made meals, obviously cooking methods do matter and in moderation.

The art and celebration part is too subjective and flys over my head completely. It's just food, do we celebrate plugging in a charger on our phones? is refueling the car an art form? No, neither is day to day eating, it's just refueling the body.

Though obviously there are people who do consider food an art and that's why this is a slightly controversial opinion.
