Being used to qwerty you (and I) would probably take months, maybe even a few years to get used to change.
But people who are only now getting into tech (and kids) can learn this layout as a first layout. Within a generation, it's possible to have people using entirely this ultra-efficient keyboard.
IMHO, the only downside, is that it does not take into consideration non-english. I use the same keyboard for English/Spanish, but I suspect that the new layout will not perform equally well on all latin-derived languages that currently use the same qwerty layout.
