30 years, perhaps more, to reach human-level AI
Wishful thinking. AI simply has bigger databases and more CPU performance and more illicitly obtained training data (in greater volume). It's still basically a fragile human written algorithm, with human curated training data using a dataflow architecture. It's updated mid 1980s techniques and can't ever deliver "real" AI.
Anything not primitively working in a lab today is usually simply a guess or wishful thinking.
Philip K Dick was a storyteller. Bladerunner is typical Hollywood. It's not researched futurology. It's Cinema entertainment loosely based on a written story.
The problem is rich greedy people (Sillycon Valley particularly) that either want to believe in Transhumanism fantasies, or think all SF is "blueprints" when most of it was warning of the environmental, social and human cost of stupidity and blindly applying technology or letting big companies have too much power.
Very many so called Tech companies are the very evil villains writers from 1890s to 1970s were warning us about. They totally miss the point of Harry Harrison, Ursula LeGuin, Robert Heinlein, Isaac Asimov, EE Doc Smyth and many others.
Cyborgism isn't the future either. The way forward is to persuade the body to regrow damaged parts. Not Six Million Dollar Man implants.
We don't even understand dog, cat, Corvid, ape or human intelligence. We don't understand why we can do language. Learning a vocabulary (signed or spoken) is not language, though proponents of teaching sign or speech to apes or parrots seem to often ignore this.
We've no AI as flexible in learning, face recognition, tool use, sound recognition, problem solving as either a common British Rook or a pre-school child. Computers can be programmed to do lots of things very difficult or impossible for a human. Programming a computer to do many apparently simple things a rook or small child can do seems to be impossible. This was known at least 40 years ago. Now marketing and exploitation wants to hide this fact!
Even the inventor of the IQ test said it didn't actually measure intelligence. It and Psychometrics are misused as simple pre-selection tools for HR (or even education).
