I always joke around that a family size bag of potato chips (crisps in some places) in 2030 will be the size of the current halloween or "snack" size bag and will contain no actual chips inside - only scent particles. I imagine a commercial where a family gathers around a tiny bag of chips, opens it on the count of 3 and then they all simultaneously take a deep breath in. then with big smiles on their faces they say "that was delicious!"
