What does this mean? It's not happened, but if we draw a line of best fit we can say we've "shown" it's likely?

The paper is "Empirically grounded technology forecasts and the energy transition"[1].

It documents "lines of best fit" spanning decades, and details the mechanism: the experience curve/learning curve/Wright's law.

Standard methods (used by the IEA, the EIA, etc.) of snapshotting manufacturing technology and extrapolating costs based on the snapshot have consistently wildly over-predicted future costs.

After reading the paper I looked at PV, and I can see how PV prices can fall to approximately a tenth of today's, by means of R&D and manufacturing improvements currently in train. That took about 50 hours, so I haven't looked at other technologies in detail yet.

Batteries and electrolysis definitely are key technologies, but R&D effort is about three decades behind PV in terms of scale at this point.
