Gene editing is still pretty crude in terms of delivery.

Just because you can hit some germ-line cells in the liver, for example, doesn’t imply you’ll have good penetration into the reproductive organs.

We can’t zap people and change all their DNA at once, unless we can intervene at the point it’s just a few cells.

The DNA was only edited in the liver. But by the time this baby grows up and starts a family, we'll probably be able to fix that, too.

That's a bold claim. The baby is 9 month old, there are many things that can still go wrong with this experimental treatment.

Hopefully not, but even then no one can say what progress will make science in the next 25 years.

Back in the 50's people thought we would be driving in flying car in 2000.

If by "they" you mean their gametes, those were not edited. Only a component of their corporal shell was modified.
