Another shower thought for you, JJG. There are many non-Bitcoiners, and some coiners who have been saying that Bitcoin has simply become too expensive for newcomers to buy. Isnt becoming clear that wallet developers, and exchanges start removing BTC as the base unit and start to use something else?
That idea of unit bias has been batted around for as long as I have been into bitcoin, so it is not exactly an innovative idea. I think Jimmy Song even had a BIP on it in 2017.. or was it 2016.. and surely there were people before him and even websites allowing for the selection of other units (fractions of a bitcoin)

Satoshis is probably going to win out because it is becoming popular, some of the other categorizations get a bit confusing in terms of which decimal point they are referring to.. but sure with anything, if one or more of them catch on, then that unit description could become widespread...
In some sense it does seem like BIG so fucking what to me depending on which problem that you are trying to solve, so sure some people are going to get confused into thinking that they need to buy a whole bitcoin or they think that bitcoin is overpriced and blah blah blah.. but in the end, those folks are pretty dumb ass fucks.. I kind of thought that for several weeks in my first studying bitcoin, so I am not even excluding myself from such camp of a person who is inclined to think in terms of the unit and to be a bit confused by the divisibility.
Another issue is that our brains are wide-spread used to accounting in positive terms rather than in decimal places, which does seem to cause satoshis to make a decent amount of sense - and we also know that divisibility beyond the satoshi (into smaller units) is already taking place on lightning network, but I believe that in order to actually transact on the mainchain, those sub-satoshi units are not recognized, so they would have to be rounded up or down to a satoshi in order to settle on the mainchain.

Not to step on JJG's toes but I think we need to start seeing more wallets exchanges display mBTC or Satoshis for sure.
0.0013 BTC is something like 75 bucks.
It just looks awkward and difficult to remember the number of zeroes.
1.3 mBTC is better or even 130,000 Satoshi for example.
Especially once BTC starts hitting the $100K or $1million territory.
I am glad to have some help responding to Wind_FURY's shower thoughts.. that's for sure.
I do agree that in your example, 130,000 is likely much easier to digest for a whole hell of a lot of people, besides mathematician nerds rather than 0.0013.... and it is probably more of a what "we" are used to kind of positive numbers thing rather than anything genetic about having difficulties with decimal places.
