I respect achievements of Poland, but at the moment, we should consider it as young country, and for such countries science don't have evidences that they will continue their success after nearest 5-10 years.
For young countries, unfortunately, very typical, to make few brave steps, and then pause development for indefinitely long time. Even possible few reverse steps.
So, Poland success, is sure hard work, but from scientific view, it is not supported by strong foundations and should be considered as fortune.
