Google plans to replace Google Assistant with Gemini, its unified generative AI system.Generative AI systems like Gemini have a fundamental flaw - they often generate inaccurate or false information due to non-deterministic responses.Despite efforts to curb confabulations, the underlying technology may always pose challenges in producing reliable virtual assistants.Gemini's implementation may lead to a world where all virtual assistants are based on generative AI, which raises concerns about their reliability.
