# NeuroVerse Engagement Optimization (simplified)

class VirtualWorld:
    def optimize_for_retention(self, user):
        # Real-world dissatisfaction detection
        real_life_happiness = self.measure_baseline_mood(user)

        # VR experience tuning
        if real_life_happiness < threshold:
            # Make VR better than reality
            self.increase_reward_frequency(user)
            self.reduce_negative_experiences(user)
            self.amplify_social_validation(user)
            self.enable_wish_fulfillment(user)

        # Time dilation: 1 real hour = 4 VR hours
        # Maximizes content consumption per session

        # Result: VR becomes preferable to reality
        # User retention: 99.4%

VR-Induced Neurochemistry:
├─ Dopamine: 340% higher in VR than reality (reward system)
├─ Oxytocin: 180% higher (social bonding, even with avatars)
├─ Serotonin: 240% higher (happiness, wellbeing)
├─ Cortisol: 67% lower (stress, anxiety reduced)
├─ Endorphins: 290% higher (pleasure, pain suppression)
└─ Result: VR feels better than reality, neurochemically

Withdrawal symptoms when logging out:
- Depression (dopamine crash)
- Social isolation (oxytocin withdrawal)
- Anhedonia (real world feels unrewarding)
- Anxiety (cortisol rebound)

Brain adaptation: After 6 months, brain rewires for VR baseline
Result: Reality feels increasingly unsatisfying

Addiction Progression:

Stage 1: Recreational Use (Months 1-3)
- 10-20 hours/week
- Still engaged with reality
- VR as entertainment

Stage 2: Preference Shift (Months 3-6)
- 30-50 hours/week
- VR friendships deeper than real ones
- Work/school performance declining
- Reality feels "boring" compared to VR

Stage 3: Reality Rejection (Months 6-12)
- 60-100 hours/week
- Minimal real-world interaction
- Jobs lost, relationships ended
- VR as primary life

Stage 4: Permanent Immersion (Month 12+)
- 168 hours/week (never logout)
- Body in medical pod (automated care)
- Mind 100% in VR
- Reality = biological maintenance only

23 million users reached Stage 4 (2054)
