Diving in current is not that big of a deal; there are a couple of easily adopted skills that you need to acquire (don't kick against the current, hide in the lee of coral and big sponges to let the group catch up, find the slowest current down on flat sand, carry an SMB in case you get separated, etc.), but most divers acclimate to conditions pretty easily.Agreed that "diving experience" can mean many different things.
Currents is an area I have almost ZERO experience, and I'm prone to cramping if I'm not careful. I'd like to get that experience at some point, but need to take a few steps to get there.
However, put me in an absolute-zero-vis open water dive where you can't see your computer 3 inches away and I've done that dozens of times. One of my favorite dives is an area with zero-vis, but tons of sunglasses and other loot, that the only way you'll find anything is by feel and effectively "dredging" the bottom. I'm fairly sure there are plenty of divers with more than 2x my experience who wouldn't do the dive I just described.
But "absolute-zero-vis" diving? I'm not doing that; you cannot make me.
