They do?

In 38 years of using disk drives I have only seen two fail, the others
all out lived the life of the computer. I have only ever had one PC
hard drive fail. It failed in the first two months.

Correction: ...and all disk drives eventually fail if left to run
indefinitely.

And houses burn down taking photo collections with them, in whatever form.

Was Falco (RIP) German or Austrian?

I would expect that difficulties with finding darkrooms will be a
quicker killer for film images than any problems encountered with
digital tech change. I have also seen problems with color degradation
with older film images.

You might as well say it works with 0s and 1s. I assume you are
aware you can describe any colour with a set of three RGB or RBY
components?

You have demonstrated a difference between black and white and
colour photography which isnt what we are talking about. In any
case I expect you could darken the blues before your conversion
to greyscale to get the same result as yellow filtered black and
white.

that's not how I would add a colour filter, I would create a
layer of the filter colour I require over the whole image or as a
grad, then blend to the required degree. boosting red would do
just that, boost red.

I think prints with good inks are the safest way to save digital
images.

That's all very well but vulnerable to tech change and your
likely failure to re back up in old age.

but not catastrophically, I have prints made by my grandfather,
dog-eared but viewable. CDs in 100 years? Unreadable due to tech
change and deterioration.

That you cannot. The RGB gamut is not as comprehensive as, e.g., CIElab.

Just had two identical drives (with near-identical serial #s) fail within a
few days of each other, a week out of warranty.

No, that has nothing to do with what I'm saying.

You cannot describe any color that way. You can only describe
individually perceptible (to human beings) colors that way.

However, that also has nothing to do with what I was saying.

It's exactly what we are talking about.

No, you can't. Try it.
