Cool article. Thanks for posting it.
I wish this had been worded differently, because it leaves the impression that 50 out of 50,000 experiments have produced successful results.
Was the author too lazy to find out how many times the experiment has been performed or did the author purposely tinker with words in order to give a negative impression?
It would be more meaningful to know how many times the experiments have been run.
I don't care about the number of hours of experimentation.
