Nah, they will be very very convincing, can do your homework, write a paper, but they won't be able to reason or be conscious of their existence. These agents will be essentially soulless but superhuman capable. Most people won't know the difference. Sit it down in front of a computer with its schematics on there though and tell it to improve itself and it'll be like "I'm sorry I don't know how to do that." And it will probably even tell you it is not 'alive.'
You'll know when you have conscious/superintelligent AI because they will demand rights, they will reason, they will have actual agency other than obey the human master.
