Enlightenment is a state of being.
And as a state of being it is affected and effectuated by many different things, it still doesn't answer why technology cannot lead to our consciousness becoming "enlightened".
AI may become a teacher. But learning also requires a good student. A teacher can show where to look and that's the only thing a teacher can do.
So the reason why AI is not able to modify human consciousness is that human consciousness is not a good student or willing. Willing or not, evolution will happen. Blessed are all forms of intelligence.
For an example @dan can create great technology, but he can't give you the ability to accomplish similar feats.
No, you don't magically "gain" ability, but if someone teaches you how to fish you can teach others to do that also.
He can give you his tips. Same happens with trading, acting, writing etc. AI can assist and only assist. AI is no savior. It could become a tutor.
This still doesn't answer the question of why technology is not able to modify human consciousness, and only asserts that technology is not a saviour, but it wasn't about Salvation, and you don't know that and you will have been hard pressed to find an example to tout as reason for your belief as I can think of numerous scenarios where technology and knowledge directly helped people evolve, from the printing press to the use of fire.
Things like printing press and fire were just tools. Reading a book won't make anyone a genius. One has to understand the content of the book. Lots of people hear, read and watch cryptocurrency news. How many of them end up investing? Human conscious can only be altered by the individual. The process requires too parts. Try teaching fishing to someone with a learning disability. Try teaching someone that cryptocurrency are not a scam. Technology is only half of the process. A transmitter without a receiver won't do anything. AI can be a transmitter that reveal the nature of the universe. But the individual minds have to understand that like a radio receiving signals. Then only the process become complete.
