Disagree. Safety is still really bad in browsers. Companies have to spend a lot of money ensuring that patches are rolled out aggressively because attacks against browsers are increasingly common in the wild. Investing into a memory safe browser would have been a huge boon, especially since security teams are often the ones who decide on a company's browser choice.
We're at the point of marginal returns on nearly all of our "traditional" tech (browsers, cell phones, gaming, etc, etc).
There just isn't room for enough improvement in the browsing experience to be "that much better" for people to switch.
