Kurtzweil's classical singularity? Probably not. Kurtz's theory was some 1990's pre dotcom irrational exuberance spunt the fuck out after snorting too many lines of moore's law and techno-messianic nonsense.

Moore's law is breaking down as we reach the physically capped size limit for transistors, so kurtzweil's singularity probably will never happen.

Now then, i will say, though, that ubiquitous computing + machine learning + psychological profiling are rapidly giving large tech companies the ability to more or less manufacture thoughts and behaviours in ways that are invisible to users, but thats not quite the singularity.

will ai help us

Well applied ai could be used to influence elections, so with the right people at the helm, sure it could. You could basically botnet an admin change to force helpful policy through...

That said, once moore's law fails completely, processing power will only increase through parallel computing...which means your ai is eventually going to need massive datacenters that smoke up energy like any other industrial site. If energy consumption is to be considered a major cause of catastrophies, then ai and advanced computer research will contribute to problems before they alleviate them.
