"To do that, the AI has to have personality. “How do you give a bot personality? It’s simple – you talk to it,” Rodichev said during a presentation at the deep-learning summit."
No, that's how you train a puppy. Unless the entity you talk to actually understands what you tell them, all you do is pile up a heap of data your expert system can work with. Granted, with rising levels of complexity (indexing, references, cross-references, parsing, sorting, collating, what have you) the system will get better and better at mimicking human behaviour. But that system will still have less of a personality than an actual puppy because it still isn't a person.
Okay, creating the equivalent of a highly functional sociopath should be possible.
Logically, this means that the first company functions that an AI could perform far better than any human are not situated at the helpdesk, but in the boardroom.
