I asked Steve Hsu (an expert) "How long do you think it will probably take for someone to create babies who will grow up to be significantly smarter than any non-genetically engineered human has ever been? Is the answer closer to 10 or 30 years?"

He said it might be technologically possible in 10 years but " who will have the guts to try it? There could easily be a decade or two lag between when it first becomes possible and when it is actually attempted."

In, say, five years someone should start a transhumanist dating service that matches people who want to genetically enhance the intelligence of their future children. Although this is certainly risky, my view is that the Fermi paradox implies we are in great danger and so should take the chance to increase the odds that we figure out a way through the great filter.
