Perhaps one day in the distant future we'll be able to go 3D - print an apple tree, or build an internet - connected modular maple tree from a kit, or have access to hyper - trees that grow at 10X the normal
rate, but
until that day arrives (and probably for long after), we'll need to keep buying young trees, planting seeds, and taking cuttings the old - fashioned way, which is actually much
simpler and cheaper than any tech solution to anything.
