Yes AI will come to replace more and more tasks and yes AI very well may take your job.
AI can do everything its purported to do, with the one exception of having actual intelligence. Nevertheless it can behave in such a manner such that people will be fooled into thinking it does possess actual intelligence and it can do many of the things otherwise thought to require actual intelligence.
If you couple advanced-enough AI with realistic-enough robotic shell, it would even be possible to pass as human. Granted we're not quite there yet but it'll get there probably sooner than you think. At that point there could be AI androids wandering the streets and it may be difficult to tell who are real humans and who are androids. I don't think our current materials science is quite there to make it look realistic enough at the moment but it will probably get there. As for the AI, it doesn't need to be perfect, as a good enough AI would likely pass, especially when you consider most people just aren't that smart, so even if the AI does a bunch of dumb things that'll just make it seem even more human, in a way.
In a future world you may very well have androids mixed in with people, and no one will know. They can be used as spies or for almost any purpose an actual human could be used for and many that humans couldn't be used for.
If you don't believe AI will take over in many areas, you are misinformed or delusional. You're flat-out wrong.
Oh and by the way, placing bans on AI (or on encryption or any other technological item) is just stupid because it's not going to stop any of that. If anything it'll just encourage it more.
Ban AI because it's "too dangerous"? Okay well you better ban computers first, because anyone with the requisite knowhow and a computer can just make their own AI. Ditto with the drones and such. Even if they're banned, people with the requisite knowhow can and will still make them from raw materials. And the same goes with guns, hence the 3D-printed guns and so on. Put all that together and you get your killer AI drones. So even if you ban all this, you don't stop the scenario from potentially occurring.
And the less stable the world becomes politically, the more likely any of this will happen at some point, and it won't necessarily be just government or enemy government agents either -- it could be anyone, and for any reason, including a lack of sanity.
This all will happen regardless of whatever laws are made. So the best thing to do isn't to ban anything, but to assess the situation and plan for the future. We need leaders who are more tech-savvy. We need citizens who are more tech-savvy.
You don't stop bad people from doing bad things by saying "Now don't do that." You have to outsmart them and you have to overpower them.
It is absolutely a game of cat and mouse and it's on.
