The biggest pressure on variant mutation right now is vaccine-evasion - so the reason the Delta variant has out-competed it is likely because the Delta variant does an even better job of evading the vaccine.

In general, I'm disappointed that we are not rolling out updated boosters with variant protection. Flu vaccines are updated each year - and here we are almost two years from the initial outbreak, and we're still vaccinating people against the original form of the virus - which isn't even spreading anymore

That's not to say that it's not still lifesaving to get the current vaccine - but F - we can do better!
