In my opinion, I don't think that the "optimal" OH has been invented yet. For example, TH solving had been around for much longer than OH solving. Even TH started with Corners First and Petrus because people just didn't have enough experience with the cube the invent the Cross or F2B. I mean, I know a lot of y'all are method developers, and would you guys have been able to think to make an cross from absolute scratch? Like how pre-historic humans made the wheel. It's simple to us but not to them. I argue that the same thing is happening now. All these so called "OH optimized methods" are just basically putting together things that are known to us like EO and CP. Like people didn't even know what EO was when it first started. I say that if people are as motivated as now to develop a new OH method, we'll discover something new like, whatever, and CFOP for OH will seem prehistoric similar to how we see people who hunt with bow and arrows.
