2000 Eure per month are sufficient, 3000 Euro per month give you some headroom, 10000 Euro per month give you much more headroom to do things you like - would you say "no"?
Put like that, no. But...what if to get that 10000 € per month, you had to move to and always stay within the city limits of Paris – not the one in France...the one in Texas. Or give up one of your kids.
So, would you still choose that extra headroom if it came with significant strings attached? Maybe you would prefer to get the additional headroom without any changes to your life situation...in that case, you could post on an Internet forum how much you'd like that extra 7000-8000 €, and hope your boss reads your posts and gives you that big raise.
I haven't spoken about additional restrictions ...
In that case, I agree...as I already stated. We've established that having more DR is desirable. Now what?
Even MORE DR of course
Touché. Yes, of course...bring on the near-noiseless sensors and 18-bit ADCs.
But, one step at a time. More DR is desirable. How exactly do we go about getting it, particularly with no additional restrictions?
Building sensors in the 3rd dimension to enhance full well capacity by a factor of 10 -> its roughly 3 times more DR at low ISOs if everything is left constant (except price due to higher production cost). I think this will happen within the next decade.
