If Bitcoin goes mainstream, do you think we will redesign the Satoshi system out of necessity? Also, another question inside

I just don't see boomers understanding satoshis and using six or seven fractional decimal numbers to pay for coffee.

Do you think it will need to fork and change for the understanding of boomers and mainstream society at large?

Also, here's a question about an ETF. 100% Bitcoin ETFs like ibit and fbtc. If Bitcoin goes up 10x, fbtc, for example, will be $900. Do you think at some point they will need to split those stocks to represent even less of a fraction of a Bitcoin in order to be obtainable?
