"Farasis would not have binding agreement with Group14 if it was not cost effective."

VW has also announced a deal with Quantum Scape. If you look around, you'll find dozens of other potential new technologies that have contracts with auto OEMs or battery manufacturers too. This is how R&D in technology businesses work. We know nothing about how cost effective it is, because they haven't published any details. All we know is that Farasis thinks it's promising enough to throw some money behind it.

At any rate, I'd emphasize the 4th point that I made above. If you think you know more about where the market is going than Benchmark Minerals (a well connected team that, collectively spend 100s of hours/week monitoring battery supply chains), then, by all means, sell your TLG shares and go invest in some of these upcoming technologies instead. Personally, I won't be concerned unless Benchmark changes their forecasts.
