Although, computers can be a big help... a computer can make things more complicated in a business. Think of it as, a computer only does what it`s instructed to do. Computers do not think! at least we are not at that stage yet AI [artificial Intelligence] but eventually someday, we will rely 100% on a computer. But the day that we do, humans are out of a JOB.
What is it that you are planning to do? your question is so vague...please explain what you are trying to accomplish?
