Better scientific understanding of the underlying process (as highlighted by this article), better pattern detection (AI), and better simulation capabilities (quantum computing) all point to accelerating progress on this front.

What makes me particularly optimistic is the wide range of scenarios in which superconductivity is observed (also highlighted in the article); different mechanisms leading to a similar result suggests much better opportunity for the existence of a room-temp SC than if it were a highly similar pattern.

Certainly such a discovery has some serendipity and luck baked in, but given these advances across the board, 5-10 years seems like a reasonable bet (then another decade or two to widespread adoption). Let's hope we don't blow everything up before then.
