I agree that a gigantic shift is required and put my hopes into mass produced SMRs. It's gonna take time and money, yes, just like the shift to EVs and renewables.
Fossil fuels is still above 80% of global primary energy, nuclear 5% and renewables excluding hydro 2%.
I really don't think putting all eggs in the solar/wind basket is good. They should of course also get heavy investments but that doesn't have to exclude nuclear. We're gonna need everything we have to end the fossil era.
