If you ask me? Mobile/WiFi internet… The way and amount of time we use our phones had changed A LOT since their diffusion. I guess the release of the iPhone changed our idea of what a phone is too
Edit: when I say modern world I’m referring to the last 50 years. So stuff like “the electricity” or “the telephone” doesn’t count.
You are making a red-herring argument.
The post’s question is: “What technology made the most impact in modern times?”
A poster says “Chemical fertilizers” and detailed the reasons.
And then you come in and say “NU-UH, IT DESTROYS THE PLANET!!!” an argument that has nothing to do with the question.
If your interpretation is that “impact” includes negative sentiment and mine did not then sure
