I'm not a believer in that timeline. There's a large distance between superconductivity in the lab and commercial application (since you specified "changes the world immensely").

E.g. MRIs still use NiTi (critical temperature of ~10 kelvins), discovered in 1962, for a number of reasons (this is in spite of MgB2 having a critical T of ~39k, ReBCO with a critical T of ~90k, and BSCCO with a critical T of ~108k):

> In this paper, we analyze conductor requirements for commercial MRI magnets beyond traditional NbTi conductors, while avoiding links to a particular magnet configuration or design decisions. Potential conductor candidates include MgB2, ReBCO and BSCCO options. The analysis shows that no MRI-ready non-NbTi conductor is commercially available at the moment. For some conductors, MRI specifications will be difficult to achieve in principle. For others, cost is a key barrier. In some cases, the prospects for developing an MRI-ready conductor are more favorable, but significant developments are still needed. The key needs include the development of... [omitted]

Unfortunately, it probably won't be as simple as "step 1 discover material, step 2 manufacture, step 3 profit".

One exciting thing that could still happen in the shorter term (if/when a promising novel "high temperature superconductor" is confirmed) is an explosion of investment into research in the area. So even if it takes decades for Material X to end up in MRI machines, there would still be a steady stream of juicy progress to read about while we wait!
There's some fusion startups successfully making >10T magnets using ReBCO tape now, so hopefully things will scale up/cost down enough to be used in MRIs.
