Also, the Arduino folks have a huge apology owed to Hernando BarragÃn for ripping him off all these years! https://arduinohistory.github....

How easy is it to lose a bunch of other peopleâ(TM)s money? Bullets and no plot. Itâ(TM)s like an executive watched someone play a video game and had a brain wave. And not a good one.

When we have a vaccine.

"how do scientists expect to modify the genetic material of every living human being so as to prevent this defect? is there some parallel technology that promises a mass-producable mutating vaccine or something equal in function?"

It's not often an easy fix, and it's not often even fixable right now.

Once the defective gene is identified, and it's CHEMICAL function is understood, scintists can attempt to make a pill that provides a similar chemical so that the metabolic pathway regains its function.

Cleft palate is a developmental problem, so its treatment would be the mother taking some kind of pill while pregnant. This is unlikly to be an easy thing to fix for a large number of reasons.
