Alphabet lost Noam Shazeer, co-lead of Google’s Gemini AI models, as he joins OpenAI. Shazeer is a key figure from the 2017 Transformer paper, essential to modern AI.

His departure marks a second major loss for Alphabet's AI team, prompting a 7% stock drop tied to earnings misses and mounting AI expenditure concerns. Alphabet plans $75 billion for AI infrastructure, but expert talent leaving raises questions about its effectiveness.

OpenAI's gain could accelerate its development as Shazeer brings invaluable experience, impacting the competitive landscape. However, the crypto market shows no reaction to this shift. Investors are increasingly wary of Alphabet's ability to retain top talent while managing extensive AI investments.
