How close are we to achieve AGI?

The notion of Artificial General Intelligence is interesting. When an Artificial Intelligence software can calculate, assess, and work on numerous tasks with the same level of integrity and intelligence as a person, this is referred to as AGI.
Despite years of study and technical advances, the area of Artificial General Intelligence has failed to produce useful results. Experimentation and study into this notion are being assessed on a regular basis in the hopes of achieving a better outcome in the near future.

Experts believe that the major reason Artificial General Intelligence has yet to be developed and implemented is that it is nearly hard to mimic the human brain.
Although neural networks are excellent at completing the complex tasks that they are given, they are not a substitute for the human brain.
