There has been a call to pause AI experiments. However, many of those who signed the letter, like Elon Musk, knew that there was no chance for a pause to be implemented. They merely wanted to be on the record for a pause.

Nick Bostrom has the most comprehensive analysis of Superintelligence scenarios, dangers and Strategies. This analysis was written a few years ago. The AI risk situation is now simplified. We do not need to consider Whole Brain Emulation or scenarios.

The main risk scenario is improving Generative AI combined with other types of Artificial Intelligence could reach superhuman intelligence. It is clear that Generative AI (ChatGPT, Bard, Palm-2, GPT-4 and later versions of Large Language Models) is the source of significantly broad and capable human and near human level artificial intelligence. The systems can also achieve super-human level intelligence in various domains. The systems are rapidly improving.
