I don't think that's a good comparison though. We shouldn't compare AI/Software to handcrafting one item, you should compare to handcrafting the machine that crafts the items.

If I knit a hat, I can sell it once, but if I make a game, I can run or sell it repeatedly.

However, I still agree with the outcome - if AI becomes even better and is economically viable - number of people handcrafting software will reduce drastically.
