What kinds of technology do lawyers use?

I am currently doing a project at school for my careers class, and they ask us what kind of technology our career needs. I have not been able to find that much information about this part of my project and help would be of great value.

How can I tell which teacher is correct about technology?

One teacher says that technology is so great, the only mistakes is human error, and computers can always perform tasks more efficiently.
Alternatively, another says that if we trust technology too much we have less confidence in our abilities, computers can lead to the wrong answers, and technology can handicap people.
Also, what is your opinion
