"Hate" is a strong word, but I don't really see the need for any of the new (post-WWI) inventions. And as most of us know, they don't bring much/anything new to the table (for us hunters), but are rather being created so that more rifles can be sold. In fact, all of the relevant inventions* were made before 1900, and some of the resulting cartridges** also saw the light of day in the late 1800's. Some others came along slightly after that, but by the start of WWI, we were pretty much done. There are a few of the higher-velocity small bores that came out in the 20's and 30's (e.g. 300 HH, 220 Swift, 22-250 etc) that may be considered relevant still.
Sure, there are a few things that have happened in the last 100 years, e.g. even better powders, primers and bullets, better optics etc, but not new cartridges as such.
Given what was available in 1914, are there really any newer cartridges that have been meaningful in a hunting perspective?
(That being said, even though I've never fired one, I have a soft spot for the 8x68S. It looks nice, and I would not mind owning one).
* self-contained metallic cartridges, jacketed bullets, smokeless powder etc.
** e.g. 8x57, 7x57, 6.5x55, 303 British, 450 NE etc
