The rollout of the lightbulb significantly reduced the economic potential of candlemakers, but it improved the quality of life for society overall. So, whether technological advancement is a "good thing" depends on which group you are in: the one with obsolete skills or the one that benefits from cheaper and/or better goods and services. Either way, the overall economy benefits from creative destruction.
I’d say many people are doing similar things ?
Less jobs is not necessarily a good thing ?
