I am innately skeptical of tech startups with huge promises and extremely limited quantifiable field results. Dumping huge quantities of chemically-reactive sand onto global coasts just sounds like it has major potential downsides.

It's promising. There's lots of promising DAC methodologies. We should pursue them.

I find stuff like the CarbonCure/Heirloom partnership more compelling, and even that I think would be foolish to bet heavily on compared to rolling out more wind/solar/EGS along with grid enhancements.
