Brian is not compulsive, he's just careful and professional.

The most important practical part of that presentation is: make prints and
keep them in a box.  I'd add to that to make the very best prints you can
using the best materials available, and match your media, particularly if
you're printing on paper with any sort of coating or finish.  If you make
them Letter or A4 size, it is not impractical to print a few sets and put
them in different places, including on different continents if necessary,
increasing their chances of survival.

Everything else Brian describes is normal common sense data management,
although it is explained unusually thoroughly and with Brian's usual
panache.

Ektachrome and colour neg film will show substantial degradation much
sooner than a good inkjet, probably in your lifetime, even if you are
already retired.

Someone should offer silver-emulsion archiving online. Any venture

I used to do this at the lab where I worked.  You need to make it very
expensive for it to be profitable.  Irrespective, that way madness lies.
 The equipment is temperamental, the materials change periodically, need to
be tested batch-by-batch, and since there is no longer any dye transfer
output possible, all you have as a printing mechanism is to scan the colour
separations and print them with a digital printer anyway...

Many labs still offer B&W negs from digital files but I don't know of any
that do colour separations anymore.
