My best teachers were not the ones who knew all the answers, but those who were deeply excited by questions they couldn't answer.

I can assure you that no string theorist would be interested in working on string theory if it were somehow permanently beyond testability. That would no longer be doing science.
Interpretation
String theory must be testable to be considered scientific; otherwise, it loses its scientific value.
In this quote, Brian Greene emphasizes the essential nature of testability in scientific theories. He suggests that if string theory could not be tested or verified through experiments, it would cease to fulfill the criteria of what constitutes science, thus highlighting the importance of empirical evidence in validating scientific ideas.
In practice
This quote could be used in a presentation on the philosophy of science during a discussion on what makes a scientific theory valid.

All mathematics is is a language that is well tuned, finely honed, to describe patterns; be it patterns in a star, which has five points that are regularly arranged, be it patterns in numbers like 2, 4, 6, 8, 10 that follow very regular progression.
According to inflation, the more than 100 billion galaxies, sparkling throughout space like heavenly diamonds, are nothing but quantum mechanics writ large across the sky. To me, this realization is one of the greatest wonders of the modern scientific age.
So: if you buy the notion that reality consists of the things in your freeze-frame mental image right now, and if you agree that your now is no more valid than the now of someone located far away in space who can move freely, then reality encompasses all of the events in spacetime.
Black holes, we all know, are these regions where if an object falls in, it can't get out, but the puzzle that many struggled with over the decades is, what happens to the information that an object contains when it falls into a black hole. Is it simply lost?
Physicists are more like avant-garde composers, willing to bend traditional rules... Mathematicians are more like classical composers.
Computer science is no more about computers than astronomy is about telescopes.
There are all kinds of interesting questions that come from a knowledge of science, which only adds to the excitement and mystery and awe of a flower.
What we eat has changed more in the last 40 years than in the previous 40,000. The survival of the current food system depends upon widespread ignorance of how it really operates.
Some experts say we are moving back to the pre-antibiotic era. No. This will be a post-antibiotic era. In terms of new replacement antibiotics, the pipeline is virtually dry. A post-antibiotic era means, in effect, an end to modern medicine as we know it. Things as common as strep throat or a child's scratched knee could once again kill.
Science has eradicated smallpox, can immunise against most previously deadly viruses, can kill most previously deadly bacteria. Theology has done nothing but talk of pestilence as the wages of sin.
It is clear that Economics, if it is to be a science at all, must be a mathematical science ... simply because it deals with quantities... As the complete theory of almost every other science involves the use of calculus, so we cannot have a true theory of Economics without its aid.
