Accelerated silicate weathering seems like the most affordable carbon capture solution that actually works, but it's still a more expensive way to decarbonize than shutting down coal fired plants or partially displacing gas-generated electricity with non-combustion electricity sources. The vast majority of countries that want to decarbonize still burn coal and gas for energy; incrementally reducing combustion of these fuels is the most cost effective incremental move for the next several years. That's why (IMO) no country is doing large scale carbon capture yet.
As for the research efforts, some privately funded work is trying to get a saleable product out of carbon capture, like turning CO2 into useful polymers or other chemicals. Accelerated silicate weathering is simpler but it also has no hope of producing any valuable outputs. It's purely a mitigation measure for CO2 that has already been emitted. I don't think that these efforts are likely to yield profitable processes, but it would be great if they did because then even countries without government decarbonization mandates could improve via private business efforts.
On the government-funded side, I think that some unproductive R&D work is being funded either due to funding bodies not being savvy enough or due to politics. Kind of like how NASA has to go forward with the Space Launch System even though it's ridiculously expensive for what it does.
