ChatGPT Group Chats Go Global But Miss the Point

OpenAI rolled out group chats globally after a week-long pilot in four countries. Up to 20 people can now collaborate with ChatGPT in shared conversations across all plan tiers: Free, Go, Plus, and Pro.

The feature works like you'd expect: tap the people icon, share an invite link, and everyone can chat together with ChatGPT jumping in when needed. You can @ mention it for responses, set custom instructions for tone, and ChatGPT even reacts with emojis. Privacy-first design means your personal memory stays separate from group chats.

We tested it with six people chatting at once. ChatGPT calculated we were 8,150 miles apart and told us it would take a triathlete 23 days nonstop to cover that distance. ChatGPT wouldn't shut up unless we explicitly @ mentioned it, which got annoying. But goofing off with friends while an intelligent AI bot chimed in was genuinely fun.

The problem? The ultimate form factor for this isn't ChatGPT. It's iMessage, where I'm already texting my friends. OpenAI needs to get ChatGPT into existing messaging apps, not ask me to move my entire social life into their app.

The Information recently reported that OpenAI leaders are concerned the average user won't see much difference between ChatGPT and Gemini. More importantly, chatbots fundamentally lack the network effects that made Facebook and Instagram sticky.

The actual network effects in AI come from Projects (Claude's killer feature) and Memories (ChatGPT's killer feature). I keep going back to Claude because that's where my projects with all my daily tasks live. It's my hub.

AI companies are realizing chatbots alone won't create defensible moats. The winner won't be the smartest model. It'll be whoever figures out how to embed AI into workflows and social networks we can't quit.

Quantum Won't Break Bitcoin in 2026 But Threat Is Real

Quantum computing likely won't crack Bitcoin in 2026. But that doesn't mean the threat isn't real. The issue isn't what quantum computers can do next year. It's what attackers are doing right now.

Nic Puckrin, crypto analyst at Coin Bureau, said: "The whole 'quantum threat to Bitcoin' narrative is 90% marketing and 10% imminent threat. We're almost certainly at least a decade away from computers that can actually break existing cryptography."

Current quantum devices have only hundreds or thousands of noisy qubits. Running a realistic attack would require millions of qubits, ultra-low error rates, and millions of sequential operations without losing coherence.

The real threat is "harvest now, decrypt later." Attackers aren't waiting for quantum computers to be ready. They're collecting encrypted data now. When the technology arrives, all that archived data becomes readable.

Sean Ren, co-founder of Sahara AI, noted: "Bad actors are already collecting as much encrypted data as possible so that, when the tech is ready, all that archived data becomes readable."

Sofiia Kireieva estimates 25-30% of all BTC, around 4 million coins, sit in vulnerable addresses with public keys already exposed onchain, ready for private-key recovery once quantum computers arrive.

In July, cryptography experts outlined a plan to replace Bitcoin's signature systems with quantum-resistant alternatives. In November, Qastle announced quantum-grade security for hot wallets.

Bottom line: No quantum doomsday in 2026. But the conversation has shifted from "if" to "when." The threat isn't imminent, but it's no longer purely theoretical.
