There is no clear cut between the things we consider alive and those that we don't. Is a virus alive? It's literally just a piece of DNA/RNA wrapped in protein membrane. It cannot move or multiply, only works as a cellular parasite. What about a single cell in a human body? Bacteria? Same can be said about consciousness and ability to think. We consider humans conscious, intelligent. What about dogs, cats, dolphins? Rats? Frogs? Insects?
Modern neural networks are certainly not intelligent, they are designed to imitate human behavior, but still several orders of magnitude behind human brain by complexity. But they are not so much behind simpler lifeforms and already more complex than cellular organisms or viruses. Last few years' advances are very impressive and this is what was achieved by progress in hardware and algorithms. Currently the complexity doubles every 1-2 years and we will certainly see further improvements in machines ability to do the tasks we consider as intelligent.
Will it ever crosses the threshold of "intelligence"? There are different opinions on this, I believe it is possible but as I said we are still very far below this threshold. If the hardware and algorithm capabilities continue to grow at the current pace, we may reach semblance of it in 1-2 decades. But it will not necessarily look like machine behaving like a human. To do that, machine has to be programmed the same way as we are "programmed" by evolution, to have our feelings, emotions, self-preservation and other innate abilities.
