Direct carbon capture is necessary if we want to have a shot at reasonable survival. Maybe it's not top priority in late 2023 when we have so many easier and faster things to do and advocate for, but in long- or even mid-term we're cooked without it even if emissions dropped to 0 today. In an eco-war economy the entire scientific community would be forced to make it work. Look up "warming in the pipeline", 6 degrees within 100 years would be the result of only the ghg we have emitted to date and we're not going to stop, like, ever.
