In as much as the use of AI is advancing day by day, there are still some certain things and activities that will really requires the supervision of humans. The use of AI cannot take over all part of the world no matter how rapid it might grow. Also, there are still some undeveloped countries which are still advancing in technologies today. So no need for panic over the use of AI.
The fact is AI can not deprive anyone of their jobs. However, someone who makes use of AI can be partially be ahead of you in certain aspects. AI can not completely work on their own without the help of human to give commands, this alone means that human service is still highly needed in a company that chooses to use AI instead of human thou the capacity will reduce. People assume that AI will just takeover human jobs without considering the other aspects of it which involves costs and high costs of maintenance.
Humans will not be completely eliminated by the emergence of AI, and humans will still be needed to manage AI. But controlling and operating AI will be much easier and less expensive than managing and controlling thousands of employees.
Regarding costs and maintenance costs, I think maintaining 100 robots will be more economical than paying monthly salaries to 100 workers. Did you know that when recruiting employees, you have to pay insurance, provide meals, allowances...there are many costs incurred when recruiting and signing contracts with official employees? That's the pressure many businesses are looking to eliminate to increase revenue, and it's also the reason they will prioritize AI if it can replace humans.
And yeah, some parts of some countries can never experience development despite its advancement. Mini companies located in areas like this can not make use of AI and succeed. Even at the peak of using AI, only few out of many companies can afford it.
If AI becomes widespread and truly delivers superior results, adoption will happen faster than we think. Like smartphones, they used to be a luxury item 10 years ago and not everyone could own them but look how easily anyone can own them these days.
