Masayoshi Son's SoftBank is committing over $60 billion to OpenAI, a move that has some insiders voicing concern about the founder's intense focus on Sam Altman's AI venture. This staggering sum underscores Son's personal fascination with artificial general intelligence and his pattern of placing massive, visionary wagers.

Son's history of outsized bets on charismatic founders like those at ARM and WeWork ended mixed. His current obsession with Altman, frequently described as 'starstruck,' amplifies unease. The sheer scale of this proposed investment dwarfs previous SoftBank Vision Fund deals, raising questions about diversification and due diligence.

While Son views this as a defining moment in tech, the internal pushback highlights a classic conflict in venture capital: founder conviction versus prudent risk management. The outcome will significantly impact SoftBank's portfolio strategy and its reputation for backing transformative, yet unproven, technologies.
