Risks and Challenges: What Should Users Watch Out For?​

Data Privacy and Security​

Across the board, AI assistants raise significant privacy concerns. Regulatory frameworks such as the European Union’s GDPR and California CCPA compel companies to offer clear user data controls, but enforcement and user understanding can lag. Some products—like Siri—process more requests on-device for this reason, but the majority of advanced processing still occurs in the cloud.
It is crucial for users to review privacy statements and opt out of non-essential data collection, especially when assistants handle sensitive communications or business data. Security researchers continue to identify potential risks in always-on listening, data sharing with third parties, and vulnerabilities in third-party integrations. Regular software updates and careful calibration of privacy settings remain vital safeguards.
Industry analysts, such as those cited by Wired and MIT Technology Review, recommend that organizations perform regular audits and encourage user training. Recent incidents, including the well-publicized Samsung data leak via AI-generated code, reinforce the necessity of strong access controls and data governance around AI tools.

AI Hallucinations and Reliability​

No mainstream AI assistant is immune to the phenomenon known as “hallucinations”—the confident presentation of factually incorrect or invented information. While the frequency and severity of such errors have generally decreased with larger models and bolt-on fact-checking agents, it remains a reality in 2025.
Most technical documentation and third-party reviews urge users to independently verify critical information. Microsoft and OpenAI, for instance, continuously stress the beta status of new features and recommend a human-in-the-loop model for vital decisions.

Bias, Fairness, and Accessibility​

Another ongoing issue is algorithmic bias—where the assistant may inadvertently reflect prejudices present in training data. OpenAI, Google, and Amazon now publish transparency reports outlining mitigation strategies, but the problem is far from solved. Users reliant on assistive technologies, or those outside the most widely spoken languages, may not always receive the same level of service.
Consumer and business organizations, including advocacy groups and standards bodies, continue to lobby for greater fairness and accessibility. The deployment of multimodal and multilingual features is a positive step, but real equity requires sustained investment in diverse training data and continuous monitoring.

Subscription Fatigue and Platform Lock-in​

Many premium features, especially those for business productivity, sit behind monthly subscription paywalls. As so-called “platform lock-in” intensifies—where optimal AI performance is reserved for users who commit to a full ecosystem—consumers and companies must carefully evaluate their options before making long-term investments.
Some users report frustration when switching assistants or platforms, finding exported data incompatible or automation routines non-transferable. Open standards and API access, supported by the likes of Microsoft and Amazon, help reduce friction but are not yet universal.
