A browser is something that 1 out of every 2 people on earth [1] use frequently. That's a lot of people! All developers in the world use a browser. Lots of them really believe in open software. Some are 10x developers. A certain percentage are literal geniuses. Exactly one is the smartest developer alive today. I get that it's hard, but smart people mobilized at global scale hard?
Starting from scratch today developers would have better tools, modern languages, and a hindsight view of what worked and what didn't in previous browsers to work with. Wouldn't that make it somewhat easier?
Say the average person loads 10 websites per day, and a less optimized browser requires 100ms more to load each page. That's 415 million hours wasted per year. Say the average person makes $4 an hour, that's 1.6 billion dollars wasted!
If every browser user donated 50 cents, that would be 2 billion dollars. Would that be enough? There are 50 people worth more than 17 billion [2], would one of them bankrolling a new browser be enough? What would it take?
