This decision is being seconded by an increasing number of physicists and highlighted by that writer.
String Theory can be used to explain an amazing array of physics features — but unfortunately, we’re left with String Theory itself being, in effect, non-resolvable. So we have “explanations” that don’t also bring us real answers.
The reporter asks:
If fewer physicists were tied to strings might some of the enduring mysteries of the universe be solved? Might we know why there is more matter than antimatter? Why the proton's mass is 1,836 times the electron's? Why the 18 key numbers in the standard model of fundamental particles have the values they do?
...and extracts the professional opinion...
"With smart people pursuing these questions, more might have been answered," says Mr. Woit. "Too few really good people have been working on anything other than string theory."
That string theory abandoned testable predictions may be its ultimate betrayal of science.
...or in other words, ST went for interesting progress rather than going for real answers, and science is (supposed to be) about finding real answers.
