I'm always reading about amazing stuff like this with modern medicine. Things that work great in lab settings: cures for cancer, organ scaffolding, regrowing teeth, etc etc.
Never hear about it again after the initial news.
"Regrowing teeth" started human trials last June. Development takes time.
And there is no single cure to cancer.

Perhaps it is because you're not a specialist—all of these things are still worked on.
Are you looking for an explanation,
or a fix,
for this?
(The fix is to consume less popular science types of sources.)
Lots of tech gets discovered, is heavily patented, and then 20 years late,r when that large first round of patents expire, people start working on and developing the tech.
