But now it's quite different with LLMs. I recently updated my code and Claude had useful recommendations.
I think the production shift from agriculture to manufacturing, or manufacturing to services, is probably a better way to understand what's happening now.
I have the same problem and I'm only 5'11" (177 cm). Size "Small" might fit at the neck/shoulders but with lots of extra fabric around my midsection, but most retailers don't carry much inventory for Small, and almost never have Extra Small. In the SF Bay Area, the small items are always out of stock.
At one point I found that clothing boutiques in the Castro tended to stock clothes for skinny guys, but those stores disappeared during the pandemic.
Now I have to go shopping in Seoul or Tokyo or NYC, but if the pants fit in the waist, they're usually too short.
BTW, being an old timer, I also hated the leetcode thing when it became a widespread thing after Google adopted the practice in the wake of The Joel (Spolsky) Test. But you know, years later when I had to go through some interviews, I did spend a few months studying it and it turned out to be pretty fun. But passing technical screenings didn't help me land a job... only connecting via my network seemed to make any difference.
Now when i refer people the recruiters don't even bother to contact them. Even though they have great resumes. Not sure what's going on.
I also found that Youtube videos are just as informative as Udemy classes, but they're not always as well structured.
The MOOCs had some pretty cool/interesting university classes that don't exist anywhere else. It's a shame those videos weren't preserved where we can access/purchase them without attending the college.
But OTOH there's a chart on this page that shows a longer term trend of nearly linear growth in US passport holder percentage from the 1990's: https://lindynewsletter.beehiiv.com/p/japan-gets-there-first...
