Most reading is probably crap, too.
> what is learned from this kind of travel is generally trivial and superficial (and thus often wrong)
Someone can learn the wrong history of a dish while still being educated by it. Broadly speaking, I’m sceptical of new experiences not yielding education outside the irredeemably incurious.
I have been on a work trips to places I really did not quite know the culture, history, or the language of, nor did I care enough to learn about them. These trips are always boring, even without the work stuff. Mass-turism is similar and most beautiful artistic achievements are just tedious extension of yet more of Disneyland forever.
I spoke a bit of Japanese when I travelled to Tokyo over 10 years ago, before the current tourist boom. I had known the history and culture for years from reading about it and studying martial arts since I was a child. I was an art student when I went to Rome, Firenze, Venice, Napoli. I could read a comic book in French when I first went to Paris, knowing of course the art historical perspective to it, but wanted to understand the culture, the feel, match it with my reading of the history.
So there’s travel and there’s travel. You can travel to your own back garden and find immense treasures, after a bit or research. Or you can go to other side of the planet and find nothing at all.

Indeed. If travel = tourism, then I agree most travel (as tourism) is superficial gives mostly trivial knowledge about a culture. If travel is "living / working abroad" or "an exchange", than, obviously it is not so trivial. And indeed, even a week as a tourist can be rich if you've read deeply on some specific aspect of the country, and that is the focus of your tourism.
I would still guess that over 90% of travel (at least among younger generations) is just shallow tourism, and people most vocal about the benefits of travel are generally just tourists pretending their shallow tourism is something more. This is the sentiment I think animates this kind of blog post / article.
EDIT: And also there is nothing wrong with liking fundamentally superficial and/or simple things. I enjoy trashy fast food and SPAM from time to time despite also happily spending many days and hours carefully preparing gourmet meals. But I don't ever pretend that enjoying SPAM is some elevated fine taste. Those who enjoy shallow tourism just have an annoying tendency to try to pretend that their "travel" somehow makes them better and/or sophisticated in some way, but, it simply does not, in the vast majority of cases.
That's not the premise of the article, it's just an example. The premise is that knowledge depends on the source of information and it's quality, and travelling is usually a rather poor source on it's own.
> the tastes, interactions, trash on the sidewalk, mysterious odors, miasamatic airs, overheard conversations all add up to a thousand times what the two paragraph history of vietnam gives you.
So what history did you learn from the smells? What did you learn about the problems and philosophy of the people? This reads more like a delussion. Travelling a locations and talking to people is valuable, but this is mainly experience, not education. What you collect is the public picture of a place and their people, not the private parts they only talk about to people they really trust. Unless you live for some decades at a place, you will not be able to learn and understand the things you can gain from a well written article explaing something and it's history. Personal experience is a lousy educator, because its lacking on so many neccesary details.
