Artifical and mimic in a sentence

If you meant in two separate sentences:

Artificial: I hate artificial intelligence, because every time I look at them, I think of global doomsday

Every time I go home after school, my younger brother will always mimic whatever I say, so yesterday I got annoyed and flung his teddy bear off the second floor

If you meant in one sentence:

My brother always wants to mimic me, so it's no surprise that he got artificial teeth after I got mine, though he didn't need it
