What Physicists Have Been Missing
An exciting new theory reconciles gravity and quantum physics. I think
it's wrong. But I may be too.

But today, the foundations of physics are a sleepy place. We're still
chewing on the same problems that we had a century ago—and all that
chewing hasn't made them any more digestible. What is dark matter? What
does quantum mechanics really mean? And why does gravity refuse to
cooperate with quantum physics? These are problems that, when I can't
sleep, I like to think have already kept Einstein up at night.

but that's about the only thing she is good at.
Don't expect solutions coming from her.
What I have been missing would have been a more honest title,
(guess she still claims to be a physicist herself)

Worriment in the situation in physics was described even earlier (in 2006) by Lee Smolin in his book “The trouble with Physics”:
‘’ . . . at least one big idea is missing. How do we find that missing idea?’’

There are really not much to worry. We do not understand physics. When I
was kid in school then half of class had difficulty to understand most elementary physics; when my kids went to school the situation was same. We are slow, dim-witted, easily distracted and short-lived. It is normal
that no one understands some higher part of physics. It is surprise that
we have figured out so lot of it.

My understanding is the creation of matter requires the creation of an equal amount of anti-matter. We see lots of matter all around, but
almost no anti-matter. Your Dirac equation doesn't help.

To know less than we don't know is the nature of most knowledge
One coud imagine from some of the recent posts of put-downs of quantum mechanics, etc. thatour current physics theory is a shambles. This
isn't the case.
The "Standard Model" (quantum chromodynamics) makes
predictions of an accuracy exceeding that of celestial mechanics, which
for a long time was the gold standard of accuracy.
That there are unanswered problems (and always will be), doesn't mean that the theory is wrong, just incomplete.
The next important advances may come from another Newton or Einstein, or perhaps just accumulated smaller steps by many, but important new theories must still retain the current level of accuracy.
