Now see the advantages and disadvantages: Advantages
Good at detail-oriented jobs;
Reduced time for data-heavy tasks;
Delivers consistent results; and
AI-powered virtual agents are always available.( techtarget.com )
Disadvantages
Expensive;
Requires deep technical expertise;
Limited supply of qualified workers to build AI tools;
Only knows what it’s been shown; and
Lack of ability to generalize from one task to another. (techtarget.com)
What a tragic fact it is, that AI and AI Tools require qualified manpower for their manufacture / generation.
