Ever increasing number of people asking Grok what every single post means. Maybe the biggest consequence of widespread AI is just turning humans into NPC prompt addicts. @grok thoughts?

9 out of 10 newsletters get stuck at 1000-2000 subscribers and/or fail in <1 year because of these 5 avoidable mistakes: 1. Spending too much time in the wrong niche Many creators with 15-25K subscribers make just $500/month. They're stuck in niches that will never scale to six figures. How do you avoid that? Set a 90-day test: "Can I get 5K subscribers & 2 sponsors while spending <$15K?" If not, pivot. Fast. 2. Not calculating subscriber LTV Almost no one tracks subscriber LTV, so they have no idea how much they can spend to acquire subscribers. They're guessing instead of growing. Tim Huelskamp was different. He left a high-paying PE job to build 1440 because his LTV math showed: • LTV per subscriber = $20 • CAC via paid ads = $2-3 (as low as $1 early) That 10-20x ROI gave him the confidence to raise debt (not VC) & grow from 50K to 500K subscribers in one year. Calculate your LTV in 3 steps: • Pick a cohort (e.g., Jan subscribers) • Track monthly open rates • Multiply opens by your revenue per open Example: 25 emails/mo at $40 CPM ($0.04 per open) Year 1 calculation: Month 1: 25 emails × 45% open rate = 11.25 opens × $0.04 = $0.45 Month 2: 25 × 40% = 10 opens × $0.04 = $0.40 Month 3: 25 × 37% = 9.25 opens × $0.04 = $0.37 Months 4-12: 25 × 35% = 8.75 opens × 9 months × $0.04 = $3.15 Year 1 LTV = $4.37 Year 2 LTV = $8.57 Rule of thumb: Spend up to 25% of LTV to acquire subscribers. So, if LTV is $8.57, keep the CAC under $2.14. 3. Avoiding paid acquisition It’s hard to build a 7 or 8-figure business relying entirely on organic growth. Why? Even top creators convert 10-20% of their social followers into newsletter subscribers. For example, Dickie Bush & Nicholas Cole have a combined ~1M social followers, are A on converting folks down to the newsletter, & have 165,000 subs (16.5% conversion). To reach 100K subscribers at this rate, you'd need 600K followers. But how many people have that kind of following? Not many. So, if you want to grow your list, your best bet is to: • Quickly convert any organic following you have • Start with small paid campaigns • Know LTV and CAC • Validate your unit economics and double down or switch niches 4. Letting ego dictate ad pricing Many creators with 30K subscribers sell ONLY 1-2 sponsorships monthly because "I won't go below $2,000!" Bot Eat Brain is an AI newsletter (acquired) that did the opposite. Initially, they sold their first spots for just $1-50 (with 15K subscribers). This smart move got sponsors in the door, proved value, and then allowed them to raise rates while building case studies for new clients. 5. Obsessing over subscriber count vs. engagement I've seen 50K-subscriber newsletters drive only 50 clicks to sponsors. No advertiser returns with metrics this poor. Sponsors care about: • Click-through rate: Aim for 0.5% • Effective CPC: $2-5 for B2C, $5-15 for B2B Focus on improving these metrics first, and you'll build a sustainable business that can scale.

More protectionist BS from Florida: new law enforces non-competes for 4 years, stifling talent mobility & innovation. Florida was never going to become a tech hub but this kind of stuff makes it even less likely. Californias ban on non-competes helped create Silicon Valley.

I predicted Cold War 2, but instead we're getting a chaotic era of overlapping alliances and rivalries. America used to be on Europe's side against Russia, but recently flipped to be on Russia's side. But America is still on India's side against China. Though America is neutral with respect to India vs. Pakistan, and China is on Pakistan's side. India is generally on Russia's side against Europe, but Europe is neutral with respect to India vs. Pakistan, and also with respect to China vs. India. This is crazier than the 1700s, man

AI will learn from ‘experience’ and self-generated real-world data rather than human-made datasets. As it understands us more, its ability to solve global challenges can be exponential.
