AI End of Holy Land

I am sure you have heard two very different points of view of Artificial Intelligence and life on earth extinction. First, some very serious computer scientists are saying that AI is nothing more than just glorified typewriters. Yes, they can create some text files and pictures but they will never become self aware. After all, they were scaring us with the rise of the machines since the first Terminator movie in 1984. Some like Sara Connor were living in fear for 40 years and we cannot live in fear for another 40 years and stop scientific progress just because someone got scared that some chat-bot was asked if it needed human help and it answered that it can perform its job best without any human interference.
Another group of scientists literally quit their six figures salary job in Google and Open AI and went to the public preaching to stop AI saying we are all going to die by the year 2030 and they want to be no part of mankind's demise. The arguments they provide are very serious, saying that those who learn computer science all their life now stop understanding what machines are doing and how they are doing it. They say it would not be possible to stop AI from destroying mankind because AI does not need to become self aware to destroy us.
