most of the population isn’t tech-savvy enough to know about different browser types, or care about which one they’re using. The reason chrome is so dominant is because it comes pre-installed on many devices, and so people just don’t bother to change it.
a bit weird, as a kid I developed a habit of making “tape swords” by taking a long piece of clear tape and rolling it into a thin tube. I still do if if I find myself with a roll of tape, it’s a good fidgeting tool.
