This still feels a long way off. I have yet to encounter a charger, not made by Tesla, that has an NACS plug.

NACS is CCS with a different plug on the end. Tesla's charging standard is to die off, CCS will be the standard going forward.
Here's a real world demonstration of a charger with J3400 plugs (aka Tesla's plug):

It works on a Chevy Bolt because it is CCS.
So what does this mean for a Tesla on an NACS charger? Do they already support CCS over that port, or is it a software update?
I know Teslas were already CCS in Europe, so I wouldn't be surprised if the software is already basically there.
Tesla version 3 superchargers already use CCS for communication between car and charger for 2019 and later vehicles.
Version 2 superchargers do not speak CCS and won't ever be opened to non-Tesla vehicles and there are certain routes where that's quite annoying. My most common road trip has 5 supercharger locations along the way with 3 of them being V2, including the most isolated charger. Even once the NACS changeover happens taking a non-tesla on that journey will be a real pain.
Tesla has not put any resources into converting V2 sites into V3s. Some of the locations have been expanded with the new additions being V3, but I haven't seen much in the way of switchover.
Older Teslas (approx 2019 and older) need a hardware update.
That is the definition of the current state.
Fortunately for the future state, they can be changed.
Everyone in the US has committed to NACS in the next couple years. The others are aware of this and if they are not completely stupid making plans. They will probably support CCS for a while in some form, but they will be doing NACS in the near future. It might be like regular/premium/diesel fuels - pumps support more than one hose (though wire is more expensive than a hose).
