I shared this article with my sister. Unfortunately I have lost faith in most people to read the full article. Within 30 seconds of sending the article she responds with "Sadly I don't know two languages! So we will focus on english together"
To me the point is to toss as much at the brain as possible. Not limit yourself or your child with monoculture.
A little empathy can go a long way. Perhaps your sister simply has different taste in reading than you do? For example, I opened the article and closed it pretty much right away because it has all the hallmarks of a clickbait nothing burger.

I wish there was a Git way of commenting even anonymously (not necessarily without auth). Then a site like this, written with Hugo, could keep all the comments and the moderation/spam could be built in with a GitHub authorization.
Well, I actually remember much of that time myself. About a year or so after that video was made I was learning to program in Fortran on the university's IBM-360 mainframe. (Learning to program was compulsory for anyone studying science, engineering and mathematics and the subject was a part of the math curriculum.)
So I was ready when the early processors, 8080/5, Z80 and 8086 arrived a few years later. In fact I was running both DR's CP/M and Tim Patterson's SCP DOS on an S-100 system around the time Microsoft bought the product and renamed it MSDOS.
I work in PHP each day. I prefer the Yii2 framework and sometimes use Symfony. For some reason I just can't get into Laravel. I tried but the rapid development speed of Yii2 really is the best for my workflow.
