I think the 8 years reference was in relation to Affirm. The issue I have with it is that Affirm and Afterpay are quite different.

Affirm offers 0% at a few select retailers to bring in customers - but otherwise they charge interest. But they don't charge late fees.

Afterpay doesn't charge interest, but obviously have a late fee model (which has been discussed on these forums enough!).

One way to look at it is it took 8-years for Affirm to get 10m customers, so it is hard going. The alternative view (which I hold) is that it has taken 2 years for Afterpay to get 5m customers - so they will no doubt hit 10m within 4-years or less (i.e. half the timeframe of Affirm). I'm not sure that makes it twice as popular but it is certainly a different growth trajectory...
