AI-Native CFO Tools Transform Finance Role
This article by a16z discusses how AI is transforming the role of the CFO and the finance function. It argues that AI removes data bottlenecks, making finance software more autonomous. This leads to smaller, higher-leverage finance teams, the emergence of 'finance engineers' who build custom tools, and a shift toward continuous planning and controls. The article highlights portfolio companies like Rillet, Concourse, and Lio, and notes that Anthropic's finance team has built 70+ AI skills, while OpenAI's finance team uses custom GPTs. The CFO is becoming a builder and architect of the company's operating system, with a growing mandate in strategic decisions.
Musk's Grok Bot to Use Rival AI Models Like Claude
Elon Musk announced that Grok Bot, an agent app from his AI unit (formerly xAI, now part of SpaceX and recently renamed SpaceXAI/SpaceXSI), will no longer rely solely on its own Grok models. Instead, it will pick 'the best back-end model for the respective task,' citing examples such as Anthropic's Claude Opus 5.5, Midjourney, and Suno. The announcement, first reported by The Information, follows user complaints about access issues. This strategic shift acknowledges that xAI's models don't lead in all areas—for instance, Claude Opus 5.5 outperforms competitors on the Artificial Analysis ranking. The move mirrors a broader industry trend of multi-model routing, as seen with Microsoft's Copilot and Perplexity, and comes despite reports of SpaceX planning $40 billion in debt for Nvidia chips.
Ethereum Researcher Warns AI Could Break Blockchain Encryption
Justin Drake, a researcher at the Ethereum Foundation, has cautioned that artificial intelligence, not just quantum computers, could break the ECDSA signature scheme used by Bitcoin and Ethereum within months. He urges the industry to adopt a 'bunker mode' migration of funds to addresses that have never signed a transaction, as their public keys remain hidden, and calls on major custodians like Binance and Tether to harden their cold storage. While Ethereum co-founder Vitalik Buterin supports long-term hash-based cryptography, he advises against panic. Critics, including Coinbase's Yehuda Lindell and Jan3's Samson Mow, label the warning overblown. Proposals like BIP-360 and BIP-361 aim to phase out vulnerable addresses but face community opposition. Both Drake and others note the traditional quantum threat (Q-Day) is decades away, but AI could accelerate the timeline.
