Will a room-temperature and ambient-pressure superconductor be used in a commercial application before 2030?

A paper submitted to arXiv on July 22, 2023, describes a new material known as LK-99 which the authors claim exhibits superconducting properties at room temperature and ambient pressure. The veracity of the results are uncertain, but if a room temperature and ambient pressure superconductor were to be developed it could revolutionize the electronics industry.

Previous efforts in high-temperature superconductivity have demonstrated superconductivity below 250 Kelvin (-23.15 degrees C; -9.67 degrees F) at 170 gigapascals (GPa) and below 138 Kelvin (-135.15 degrees C; -211.27 degrees F) at atmospheric pressure. Recent research has claimed to achieve superconductivity at 294 Kelvin (-20.85 degrees C; 69.53 degrees F) at 1 GPa, however the veracity of this claim has been called into question.
