It won't replace them completely, 47% of jobs will be replaced by robots in the future.
Compared with the human brain, AI algorithms can cope with numerical and symbolic calculations more accurately and quickly, stably and reliably. Especially for computational problems with defined rules, AI can far exceed the computational speed of the human brain, and it is also easier to find the optimal answer. For example, in numerical computation, recognition of graphics, speech, biometric features, behavioral gestures, and even more complex predictive reasoning tasks, AI has excellent performance beyond the human brain.
Artificial intelligence does not have the perceptual thinking to cross over into the realm of consciousness. Current computer architectures and programming models are inherently inferior, making it impossible for AI to achieve natural interaction with the human brain's emotions, will, state of mind, moods, and experiences. Essentially, AI is merely a concept in the realm of the material world and cannot cross over into the realm of consciousness.

In a work scenario where AI is truly realized, traditional laborers aren't 'laid off' either, they just change roles. Humans would still be needed to monitor AI performance, conduct intelligence gathering and analysis, as well as carry out predictive experimentation and evaluation, and guided process management and control.
It is believed that in the future more than 90 percent of human work will be provided by AI, just as today most of our work is provided by computers and various other machines.
