Best Buy has an inventory turnover ratio of approximately 6* - So clears its entire stock on average every 8 weeks. While there might be a large percentage of USB-A products currently, once a technology market shifts it's quite surprising how fast suppliers will also change their product supply and you see a fairly rapid change in stock even in big box stores.
Most of the devices I have purchased in the last year have been USB-C. Sony headphones, LG display, my car even has USB-C charge ports. Look at many manufacture lineups and the new flagships are USB-C. I do still have a bunch of USB-A devices, but they're older buys at this point.
I think there will be a few year gap, but 10 years might be a little too pessimistic. Time will tell I guess!
Well we're already 3 years in since the new generation USB-C only Macbook Pro came out. Let's call it 7 years for a total of 10. Not putting a lone USB-A port on it was an act of extreme arrogance imho
