Yes, with the development of technology, it actually makes it easier for us at work, so jobs that usually take hours, now can only be done quickly, and there are many benefits of current technology.
Do you not realize it, there are indeed many workplaces currently that have relied on technology that was originally carried out by humans. With the elimination of human workers, it will make the unemployment rate increase. Technological developments are indeed very positive, but if more and more workers are laid off because of the system of reducing employees, then the development of technology in employment is very detrimental.
Good point, except you're neglecting the bigger pictures. Technology, machines that are replacing workers need workers to make them, service them, sell them. In actual fact, the jobs aren't lost, they're just moved from one sector to the other. That said, society has to facilitate workers' adaptation to these new skills, retraining, and upgrading to keep them relevant.
