In many countries, these and other jobs show you cannot. If you don't, others will and so you won't have a job very soon. Especially if these types of jobs lose their shine/prestige and are basically call center quality/pay like jobs in 5-10 years.

I'd love to believe that, but unless our timeline is disrupted (world war / climate change / regulation re: power generation and consumption), I unfortunately can't imagine a future different to the one I described - and I've tried!
