Research is research. Future units will be more efficient.
Looking at this and extrapolating to the future is like looking at a model T and assuming you could predict modern car culture. Simply multiplying is both misleading and misses the point.
The reality is we need to look at and try all potential remediations, and one is not exclusive of others. Direct carbon capture doesn't mean we aren't also looking at conservation and other mechanisms.
The unfortunate reality is we need to not simply stop dumping carbon into the atmosphere - we need to reverse the flow. Carbon capture and sequestration technologies is that process, and needs to happen *in addition to* conservation.
I suspect the eventual efficient solution will be something not invented yet. But to get there we need to iterate on what we can achieve. This isn't a solution - it's part of a process.
