The block size is a sensitive topic, as it has been used as an attack
vector in the past.  It is now a loaded topic baked into the mythology of
the project.  Discourse on the topic benefit from a dispassionate analysis
of the technical trade-offs and what properties of the network they affect.

There exists an attack on bitcoin where the lowest fee rises to make it
much harder to participate.  You could imagine a well funded attack,
creating fees of, say, 10,000 sats/vbyte, for a period of time.

While this could be viewed as positive from one lens (miners benefit),
there would at least be a vocal minority, legitimately arguing that this is
disruptive to the ordinary function of the network.

It's worth recognizing that a bigger block size makes this kind of
disruptive attack more expensive.

It's a tricky topic because of the history, and because some of the "spam"
may be seen by some as legitimate.

I think in the long-term miners and users will treat the fee auction in new
ways, with the use of AI algorithms.  Trillions are transmitted through the
bitcoin network.  A fraction of that is captured.  As the block subsidy
goes away over the next 2 decades, it might lead to a kind of "AI mexican
standoff" where the highest value transactions pay a bit more for priority
transfers.  AI will likely change the game theory, and we'll find out how,
over the next 2 epochs.

If that is the case, then block size can increase with hardware advances,
while maintaining much valued decentralized properties of the network.  In
this regard we probably would benefit from things like stratumv2 and
utreexo being rolled out first.
