What's happened, historically, is that as a technology diffuses into new ways of doing things, old industries simply die out, and then the new industry differentiates into replacements for it. Specialized production in the middle ages was divided into guilds (many of which are family names now): you had smiths, cobblers, bakers, butchers, weavers, etc. When the industrial revolution happened, there was simply "industry"; it was only later that this differentiated into the steel industry to replace smiths, the meatpacking industry to replace butchers, the textile industry to replace weavers, etc.
Similarly, when software got started in the 50s, there was only the "software industry". Now, 60 years later, it's differentiating into search, social, messaging, e-commerce, developer tools, homesharing, adtech, fintech, ridesharing, delivery, etc. And it's likely there's more to come: if I had to locate us in the history of the industrial revolution, I'd say we're around 1890 or 1900. At that point, the great industries of the mechanical age (mass-produced automobiles, airlines, plastics, radio, television, recorded music) had yet to be invented.
