Challenges 17

Mature User Understanding Text processing Question answering Domain-specific datasets and ontologies Graceful fallback 18

Legal Challenges Inherently error prone: are they legally binding? Accounting for false-positives and false-negatives The case of 3rd party PriBots: defamation possibilities? 19

Trusting the Machine rule-based vs. AI-based user backlash? regulate the confidence level 20

PriBots’ Personality positive tone → higher trust diversified content → reduced habituation 21
