>Natural gas has already fulfilled its usefulness as a “bridge fuel” Seeing how Poland still gets approximately 70% of its electricity from coal, I wouldn't say so. Also until the grid-scale storage problem (at least on the level of storing several days of grid consumption) will not be properly solved (personally I am fan of underground pumped hydro storage built on top of artificially dug cavities), I don't think we will see large predominantly renewable grids not backed up by natural gas power plants. And don't forget that natural gas consumption is not only about electricity. But also about heat generation (both in households and industry) and production of various chemicals.
