MAKE MONEY WITH AI
Turn AI Into Extra Income
You don’t need to be a coder to make AI work for you. Subscribe to Mindstream and get 200+ proven ideas showing how real people are using ChatGPT, Midjourney, and other tools to earn on the side.
From small wins to full-on ventures, this guide helps you turn AI skills into real results, without the overwhelm.
LATEST DEVELOPMENTS
OpenAI launched direct controls to adjust ChatGPT’s warmth and enthusiasm, letting users and teams set consistent tone presets, with admin policies and API parameters for developers.
Details
Feature rollout: Sliders let you tune ChatGPT’s warmth and enthusiasm per chat or as a default setting.
Presets: Save tone presets to keep responses consistent across conversations and projects.
Context-aware usage: Apply different tones for tasks (e.g., formal for reports, upbeat for brainstorming).
Enterprise controls: Admins can set org-wide tone policies, enforce defaults, or limit adjustments.
API support: Developers get parameters to programmatically set tone for apps and workflows.
Guardrails unchanged: Safety and factuality systems remain; tone controls don’t override safeguards.
Takeaway: Direct tone controls make ChatGPT more adaptable and consistent, use presets for your brand voice, and enforce policies at team scale.
Humanoid robot demos outpace real capabilities. Practical robots win in factories today; humanshape adds cost and complexity with little payoff. Timelines are optimistic; real deployment is rare.
Details
Claim vs. reality: Demos: Polished videos and staged trials. Reality: Limited dexterity, slow movement, short battery life.
Form-factor trade-offs: Human-shape: Expensive, complex, fragile. Alternatives: Wheels, arms, and carts outperform in warehouses.
Use cases today: Viable tasks: Repetitive, structured workflows. Gaps: Unstructured handling, clutter, and edge cases.
Economics: Costs: High unit price and maintenance. ROI: Hard to beat mature non-humanoid systems and cheap labor.
Timelines: Promises: “Years away.” Pattern: Slips and pilot purgatory; few sustained deployments.
Workforce impact: Near-term: Augmentation, not replacement. Need: Training, safety standards, and realistic expectations.
Takeaway: Focus on robots that solve specific jobs well. Humanoid hype is loud, but utility, reliability, and economics, today, favor simpler, non-humanoid machines.
Companies increasingly use AI chatbots and one-way video to screen candidates; success hinges on energy, keywords, structured answers, and awareness of AI scoring and bias.
Details
Expect AI-led screens: First rounds may be one-way video or chatbot interviews; treat them like real interviews.
Project energy on camera: Practice to avoid the “feedback void,” keep eye contact, and minimize note-reading cues that AI may flag.
Use role keywords: Chatbots parse for job-description concepts and positive framing; give concise, content-rich answers beyond yes/no.
Apply structured frameworks: Use STAR (or CAR/SMART) for situational questions to deliver clear context, actions, and results.
Know scoring and bias risks: AI generates composite scores for recruiters; systems can amplify first impressions and may disadvantage nonnative speakers.
Takeaway: Match the job’s keywords, speak with energy, and structure every answer, then let the AI scoring get you to the human.
