Interesting in a chilling kind of way. I'm not sure it's hyperbole to suggest that Ireland's reign as "nation to have taken best advantage of the pro era" is not only about to end but is about to be trampled into dust by a stampede of Boks.
The context:
1) 2 SA sides in their inaugural URC final. Virtually no Springboks in either side. It took them precisely 6 months to fit in at the top of the league.
2) Currie Cup still alive below URC to broaden talent/playing pool around entire country
3) Schools system to rival Ireland's, but on a much larger scale
4) Participation rates about to explode into the non-Afrikaans pop. Already bearing huge fruit but will get exponentially bigger
5) Access to the H-Cup for the URC 3, Challenge Cup for the Cheetahs (prelude for Cheetahs' inclusion into URC?)
6) Overseas Springboks now playing in URC, ERC, Prem, T14, Sup, Japan
7) SA to play in 6N from 2025

9) SA with their own CVC deal, who will ensure this global participation happens
10) URC to start paying SARU from 2025. Supersport TV deal independent or rolled up in URC obligations?
If it works out as described in the interview and as seemingly already agreed (with the influence of CVC) S Africa is about to start an era whereby they are strategically positioned everywhere, dominating the sharp end of the competitions they participate in, fed by a near-limitless supply of increasingly-athletic players and paid by several global competitions at club and national level.
While they love the Currie Cup, they don't have the hangups England and France have about their domestic leagues, aren't as precious as NZ and - unlike OZ - union is overwhelming king.
The only things that can realistically hold them back are the rand, corruption/incompetence at board level (a la Stormers) or a temporary dip in the player pipeline.
Other than that, they've comfortably supplanted Ireland as the jammy nation with undue influence and are prob less than a decade from hegemony at a level we haven't really seen before in pro rugby.
