That's silly, zero sum thinking. Unless the market for a good is saturated (everyone who would buy it will), making the production process more efficient creates both wealth and (often) new jobs as the producing company can now grow. As an example, imagine someone develops a bit of tech that improves software development by 100%. Would a dev shop with this tech fire half their programmers, or would they expand their speed and scope and grow faster as a result?
