There's a "no news" zone between a discovery and proliferation. In 1997, deep blue become superhuman.. proving the point. The average consumer engine was still like average tournament player with really weird moves. It took another decade before superhuman engines became widely available to normal people.

That decade gap is where we often mispredict the future. Once a point is proven, we expect instant impact. Reality takes time.

It took 15-20 years after superhuman chess engines were invented before they really impacted chess. Cheating is one impact, but novelty is another one. "Computer moves" are learned by GMs and played in world class tournaments. Contributing novelties is a mark of influence in chess. Even computer strategies are starting to appear in human tournaments.
