Edit: A lot of people seem to hate on the article without reading it.
Here is a supporting scientific source, by the same author: https://www.sciencedirect.com/science/article/pii/S2666188825000863
The environmental impact of our online habits is far larger than most realize, and as digital communication continues to evolve, we must consider its long-term consequences on the environment and human life. We should take the easy steps of cutting wasteful energy use in our communications and it can start with eliminating email signatures.
Paraphrasing a bit from the scientific source:
If the population of Canada used email signatures for a year, ~30 people in developing countries will suffer a premature death within the next 100 years.
That 100% should have been in the article in some clear form or another.
I’m not against the points of the article, I’m against it being so poorly written that AI slop is just as good.
