Well, we can thank our lucky stars that cuttings aren't like cassettes, or, heaven help us, 8-tracks! On the other hand, the guy who invented the 8 track was Bill Lear, yep- the dude who started Learjet. Props for workin' your way up, brother.
As far as cuttings are concerned, it's the only known way to preserve the original pheno. Want an extreme example? Every variety of apple, including all the crabapples, are ALL cuttings taken from one original tree that showed those characteristics. If you toss some apple seeds in the ground, what comes up bears little resemblance to the original because apple trees don't run true to type. How long do you suppose granny smith, fuji or red delicious apples have been around, cut and grafted over and over again, without the mythical 'genetic drift'? Longer than any of us, and then some...
There are plenty of varieties of cannabis out there that are available as a 'cutting only' for a reason; that was the only pheno the Original Grower thought was worth saving, and so that's how they get passed around.
