This is taking over faster than I ever expected, with some places already doing the race to the bottom (I recently discovered a portal for small businesses is now offering AI call answering / support / booking all automated addon for $10 / month - and I thought it was a good deal offering similar for $500 / month not long ago), this is going to make millions obsolete within months.
And I only say months because I see it taking that long for places to wind down contracts and switch over to AI call answering and customer support.
The ai systems available for so many of these tasks are more than good enough, and so many people and even tiny businesses are now aware of their existence, I don't see any going back to non English as first language call answering, support or even IT help at this point (for US based businesses, which I assume has been the lions share of income for many of the call centers in many places).
Consider: There are still things that can't be self-serviced on the INTERNET - anything with moderate complexity or risk.
