Information technology and the whole digital age has of course had a negative effect on those jobs that were entry level or required only manual skill. Jobs have been killed but new jobs have been created and these need to be studied for and offered to people willing to retrain and reorient themselves.
Information technology does kill jobs to an extent. The smarter computers we have the less we actually have to do as people and the more they start to take over mindless job. However, someone still needs to create those computers and monitor them from time to time to make sure they are right.
No, information technology does not kill jobs, because it has transformed jobs, and created job in new fields. With the invention of computers, employers need people to run them. With information technology, employers need to hire someone to manage the network, and respond to customers who contact the business via email.
Information technology can kill jobs but it also has the potential to create others. For example, years ago there were factories that made VHS tapes and VHS players. They made Cassette players and other items. Those jobs are now gone, but then now we also have new jobs like bloggers, YouTubers, and podcasters which didn't exist before either.
I do not believe information technology kills jobs, I believe it creates new jobs. We have many, many people in the information technology industry that would not have been able to have picked that career field 30 or 40 years ago. These people are benefiting from the information technology boom and are employeed because of it.
