The main part for me is reducing error faster as they scale. This was a major road-block, known as "below threshold”. That's a major achievement.

I am not sure about RCS as the benchmark as not sure how useful that is in practice. It just produced really nice numbers. If I had a few billions of pocket change around, would I buy this to run RCS really fast? -Nah, probably not. I'll get more excited when they factor numbers at a rate that would break public key crypto. For that would spend my pocket change!
