That is the ONLY topic here.
You are just running it off in a direction that suits your agenda.
There is a point of diminishing returns due to practicality. You cannot put a marine engine in your hatch back can you now.
I'm off, you are just trying to sway this in a different direction to push a point that is not relevant to the original statement.
Boost doesn't replace displacement. The phrase is not speaking in terms of practicality, that is your own addition to it to suit your own agenda.
Size matters. The point I'm making also
does matter because IQ out of m4/3 can't equal the IQ out of say a 645Z, otherwise no one would buy a pricey and ginormous 645Z or Hassleblad Medium Format kit. Obviously, the Medium Format has better quality and the resolution can scale higher amongst other aspects.
This doesn't consider size, weight, price, just sheer quality of the image and you may not need the extra resolution or light gaining ability. Nor does the phrase 'no replacement for displacement' consider those aspects.. it is simply saying that size matters. End of story.
