As of November 29, 2025, there is no verified, commercially relevant superconducting technology that enables practical zero‑resistance electrical conduction at ambient conditions and has materially transformed global energy and power systems.

Key points from current evidence:

• The most publicized recent claim of a ‘breakthrough’ superconductor was LK‑99 (a proposed room‑temperature, ambient‑pressure superconducting material) in 2023, but multiple independent groups failed to reproduce true superconductivity; follow‑up studies concluded its behavior was not consistent with a genuine superconductor.
• High‑temperature hydride superconductors (like various hydrogen‑rich compounds under extreme pressures) have been reported at or near room temperature, but they require gigantic pressures (hundreds of gigapascals), making them far from practical commercial technologies for the grid or general power applications.
• There is no evidence in energy‑sector reports, major physics/engineering literature, or mainstream coverage that any immigrant in the U.S. (or anyone else) has produced a widely deployed, transforming technology based on practical zero‑resistance conduction.

However, the prediction’s time horizon is “within the next few decades.” Only a few years (2021→2025) have elapsed, which is far shorter than the stated window. Since the prediction explicitly allows multiple decades for the breakthrough to occur and diffuse enough to transform global energy systems, it is too early to judge it as either right or wrong.

Therefore, given the long timeframe and current lack of such a breakthrough, the correct assessment as of today is inconclusive (too early to tell).
