I think a meaningful "sustainability" goal could be to build devices that can last longer and be used longer without the need to buy the "latest" gadget. Building robust software and hardware should be part of that thinking.
On a side note a younger kid in family used this unix tool called "sed" and asked me if such advanced tools existed during "my time". I told her I was not born even after 10 years had passed since its invention.
Absolutely! It's barely touched on in the article, but it's the first "R" in reduce, reuse, recycle. By reducing our need to consume because we want updates or need security patches, we don't need to buy a phone every couple of years.
Together with the EU's replaceable battery law, this is a good step in that direction.
Unfortunately it pushes against planned obsolescence which makes companies more money, so we'll see how long the promise of updates lasts...
