There is a lot of value in learning about different cultures by physically travelling, but I think there are other options now. I believe the hyper-globalization of society due to technology allows many more people to experience other cultures without needing to travel. It's up to individuals to take advantage of it and lean into certain discomforts.
I don't believe it's possible to integrate with modern society successfully without having to go through some kind of culture shock. It's not limited to culture defined by regions, older generations feel culture shock constantly when trying to stay integrated or understand the culture of new generations. But things like YouTube have allowed me to experience culture in a way that wasn't possible 20+ years ago.
I have been loving the relatively recent trend of older people, parents and grandparents making cooking videos. I recently found De mi Rancho a Tu Cocina, a channel where Doña Ángela, a 72 year old grandma teaches Mexican recipes. The channel has 4.2 million subscribers and the first video was uploaded in August 2019 and hit 2M subscribers by December 2019. Very simple production value, except the wood fire cooking which is probably out of necessity as she lives on a ranch. A similar channel with more production value, but still very homey is Cowboy Kent Rollins, 2.32M subs, who is verified on YouTube and has built a brand and a merch shop related to outdoor cooking. I grew up in the suburbs in the tristate area, but love making myself traditional style Mexican and TexMex food, homemade refried beans is a favorite.
