Answer:
Computarization and systematization of the workplace with the use of computers has changed the way that jobs in general are performed. From simply being a housekeeper at a hotel, to being a CEO, in a huge company, there are very few jobs that have not been affected by the appearance of computers.
However, there are some of these that used to be much riskier, and much more dangerous, and which changed with the appearance of computarization. The reason? Because computers made mechanization possible without risking human integrity, because computers allowed to see beyond what the human eye can, they are more exact in their functions, and they cannot be damaged the way a person can during certain activities.
Some of these jobs are:
Assembly-line and factory workers. Probably one of the biggest examples. Machines, led by computer systems, now perform tasks that in the past caused human lives and limbs.
Medical professionals: Computer made certain practices in medicine much more efficient, and less risky, especially laboratory and diagnostic testing procedures, where people once were exposed to dangerous substances, and now, thanks to computers, is not necessary.
Engineers: Be them mechanical, civic, chemical, or any other type of engineering, computarization also impacted this branch of knowledge because it mechanized procedures that could be dangerous, like assembly of parts in a bridge, or an airplane, or even a ship. Now, these procedures are done by computarized technology, and people just control the computers.
There are many more examples, but these are a few I can think of.
