The GP was (rightly) calling out the over-the-top assertion that anyone who isn't on the internet is of no value. If that's not condescending and hyperbolic, I don't know what is.
To a certain extent, yes. Lack of internet access is a serious form of social exclusion, similar to having limited literacy or lacking a bank account. You'll have problems accessing government services and essential information, you'll be unable to find or apply for many jobs, you'll pay a premium for many goods and services.
My town has no brick-and-mortar travel agents or bookstores. Most of the bank branches have closed. Our local housing association only advertises vacancies online. People who don't use the internet are now effectively an underclass; our government is quite rightly working towards 100% internet access.
Pretty condescending and representative of the HN bubble when you consider this fact: 13% of adult Americans never use the Internet.
