These discussions concerning the impact that higher-resolution files with higher file sizes have on processing is quite grounded in reality, but also quite silly.
I'm a computer geek. I've been one since I was 10, and that was a long, long time ago (for me, I'm not that old), but I do remember when Windows was something you started from a prompt. I've been building computers since then and have no problem assembling something imminently powerful for whatever purpose, to the limits that are available to consumers.
You can imagine that I think this discussion, as I said above, is silly; just build a faster computer. Need more cores? Easy. More RAM? That's cheap. Storage? Like a boss.
If I need more clockspeed, I'll slap some better cooling on it and tighten down the screws. I can do that.
And I can't see how this is a problem for any of you- if you can afford this thing, and even if you're married to Apple (and that's not a bad thing, for the line of work involved), there are straightforward solutions out there.
It really should not be a part of the discussion, beyond recognizing that we'll need a little more 'whatever'. We do that all the time anyway. Move and talk about how this product could add to your photography, and photography in general, please!
