I think the article may have been written half tongue in cheek - I expect if I was British, instead of just Canadian, I might have more fully appreciated the humor. Hints were as follows:
" If a burglar enters your home, you can drop your typewriter on them from above"
"To get the most out of Google Docs, you must use an arcane device known as a mouse. "
But, if you read the article all the way to the end, there are actually some parts that cause you to think about the (particularly for the ADHD among us) issue of using Google Docs as our principal text entry / editting tool (as opposed to something like "Pages" in Full Screen mode)
As for the earlier suggestion that I should retire, I most certainly would like to, but I'm in my twenties (it is perfectly possible to have used a typewriter frequently as a child and now be in one's twenties). Old school doesn't equal old. I'm a programmer in my spare time and do independent development projects to pay my way through philosophy grad school. I think Google Docs has a perfect use - I use it a fair amount for planning (the podcast I'm involved in uses it, and we used it quite a lot to plan a vacation). I'm not advocating using a typewriter instead of Eclipse or instead of whatever you use for word processing. What I'd like is if some of my geek friends would learn the lessons of technological history and maybe try some of the old tech they think desperately needs to be deprecated in order to bring about some technological paradise. It's not all bad.
I'm not opposed to technological change. I'm opposed to people thinking technology is automatically good because it is new and automatically needs to be made obselete because it is old.
It's tongue in cheek, and the point of the article (as stated early on) is that when changing tools there are always advantages and disadvantages.
The author then goes on to demonstrate that there are plausible disadvantages even for something as implausible and absurd as using a mechanical typewriter instead of a word processor.
tldr: It's painfully apparent the author is getting too old to Keep Up and is taking that frustration out on newer technology. Retire already. No one uses gopher or typewriters anymore (for serious work), nor will they ever.
