Like everything in the software world, because some Google engineers used it, it became world wide famous. There's a saying in german that I love, basically amounting to, "they also cook with water". In short, there is no real tool that has "secret sauce" or is "super magical". It's an editor, that's all.
Say what you will but nano is is fine for me via SSH, VS Code for everything else.
Looks like many of the comments take a similar stance, which I'm actually surprised at.
