This is a question that come up from time to time. So I will just give you couple of perspectives.
First thing first: you should first ask what "A.I." are we talking about. A lot of times, when people are talking about machine are taking jobs away from people, they are really talking about "automation" is taking away the jobs. Now "automation" just means something can be done without human interference, it might or might not have to do with A.I. For example, I can write a for-loop to repeat something for 1 million times. But no one would call it "A.I.", "programming" may be. So in that sense automobile, large-scale industry equipment are all "automations".
This is an important note because to determine if jobs are really taken away from humans, we need to look at economic data, but so far, there is not many reports which are really on "A.I"'s impact. But there are many studies which look at the impact of "automation", then they will say "Oh, AI in recent years have been helping automation" but they usually don't quantify the impact.
Now then there is the idea of this supreme AI being (or AGI) will control everything in the world. Valeria Iegorova said it well, we are just far far away from that scenario. Just imagine you want to automate the manual work by a construction worker - creating a biepedal robot with the capability to walk around a construction site is a billion dollar project. Not to say to ask them actually do work.
So why would so many people fear about A.I. steal away their jobs then? Well, many of those who complains are really unemployed because of various reasons. May be their industry is just no longer appropriate for the time.
Now are there any cases where A.I. are replacing humans? Yes. But their economists will tell you a long-known fact - with proper re-training, humans can quite easily get back to workforce. So you might here a lot of more senior citizens these days are learning programming and get hired. These are usually incentivized by governments. In an other words - if you live in a place governments sense unemployment issues early, they will usually come up with reasonable solutions to resolve the problem.
Hope this is not too long. But I think it covers the topic. Other than that, good luck!
