A similar sentiment was expressed when Eli Whitney introduced the cotton gin. It was massively disruptive and work changed from individuals at home to (global) collectives and factories where clothes are created. There are countless other examples, but that is by far my favourite. The more interesting question will be the impact of globalization on salaries and competition. Logically either efficiency and value provided by high cost of living areas continues to increase (and dramatically), or lower cost of living areas accelerate. We're already seeing this in many parts of the world. We should assume that over time that salaries (for tech) decrease in North America over time, or at least increase at a slower rate than those of the rest of the world. Similarly the salaries elsewhere will increase over time. While slow - this is the ongoing truism of economic migration.
