A couple of years ago Y. Tokura listed several key challenges to materials science, which would lead to important breakthroughs in achieving sustainability. He argued that one should look for the answers to materials with strongly correlated electrons. One of the challenges is to realize a working superconductor at room temperature The discovery of superconductivity in the strongly correlated cuprates brought a dramatic increase in the transition temperature. Regrettably, in the intervening quarter century no further increase was achieved and the highest Tc remains well below room temperature. Even today there is no clear roadmap or guideline to further progress in raising Tc. This talk will focus on the special conditions that exist in cuprates and the difficulties of reproducing them in other transition metal compounds.
