I'm not talking about tweaking color, I'm talking resolution, film speed etc.
While you can increase the "film speed" with a digital camera as well, you can't
tweak resolution. You have to use what you have, which may or may not be enough.

Absolutely agreed. They would be crazy not to use digital technology. Digital
has a lot of advantages and this is one of them. It sees also great use in
astronomy, where digital sensors - extremely expensive ones, BTW - do the job
that film did in the past. And they do it much better than film ever could.

No, I can't. But I don't need to, because I'm not involved in a space flight
(yet). And that saves me quite a bit of money and image quality.

As do I, at least I try to do so real hard. But I can't ignore simple physical
and economical facts, as much as I'm excited about the potential of digital
photography. I took digital images more than a decade before the first
generation of digital consumer cameras hit the market. And I've written filtering,
image enhancing, measuring and classification algorithms long before the
Photoshop era :-) When I say today digital is expensive, it is *dirt cheap*
compared to back then. The first system I worked with had a storage that filled
a whole rack and was able to store two images of size 512x784 of 8 bit data.
It cost more than $100K at that time. Today, every cheap consumer digital does
a lot better.
