Carbon prints are both more stable and have a wider possible tonal range than platinum prints do. I’m not sure where he got the idea that platinum prints have a wide tonal range from. While they have exquisite highlight separation, they tend to have a rather compressed, flat tonal range. The dimensionality he talks about due to the emulsion sinking into the paper fibers is also a reason for the compressed tonal range.

Very few people use pure platinum salts. Most prefer a mix of platinum and palladium to get better darker tones. It is also more likely that vintage “platinum” prints are probably platinum toned Kallitypes.

All of the positive things he attributes to platinum prints are probably better applied to carbon prints. I think carbon is the ultimate printing medium for monotone photographs. Maximum control of tonal range, detail, and the best longevity.
