My honest answer? No one asked you specifically to care. Other people care. If you don't enjoy JAV and don't want to see more of it, then this isn't for you, and that's fine.
I don't know whether you use haptics, but the same data collection will be used to automate script generation, so more scenes can be scripted more quickly. It's currently a massive time suck to do it manually, and they could script so many more scenes with automation. (That's the second part he was referring to.)
Again, if it's not for you, groovy. But there are people, myself included, who are very excited about how this tech can be used to further our creative goals.
