Are you sure? That sort of statement is hard to answer because it doesn't
say what you think long term is, or how much you expect Bitcoin to grow.

Satoshi thought it was a perfectly fine long term solution because he
thought hardware would get cheaper as fast or faster than Bitcoin would
grow. You may disagree with him, but as we're talking about the future are
you 100% certain he was wrong? I did calculations a long time ago that
suggested even with today's hardware (+some software optimisations) it
would be feasible to keep up with Visa.

Hardware improvements can be unintuitive. There's a spreadsheet here that
lets you play with various parameters.

(note: the spreadsheet says avg txn size is 250 bytes, but if you check the
formula for the middle column, it does actually use 500 bytes as the
multiplier hard coded).

That's not clear either, I'm afraid.

Remember that there's an upper limit on how high Bitcoin fees can go. When
fees become higher than what the banking system charges, many users won't
use Bitcoin for moving money around anymore. Fees cannot really go much
higher than that even if you assume the currency is still attractive for
other reasons, because people would just sell their coins for fiat, move
the fiat, and buy back the coins the other side.

The way mining will be funded in future is an open question. There are
differing proposals. Still, even with a higher hard block size limit,
miners can always refuse to mine transactions that don't include a
particular fee. So if you're worried about this, miners aren't being forced
into any particular policy.
