OpenAI just announced the prototype of a search engine called SearchGPT that now puts the pressure on Google, with what the startup says are more natural and intuitive results that include sources, similar to a product from Perplexity AI. The announcement alone yesterday was enough to send shares of Google down 3% after it had already been bruised by disappointing earnings results. That also doesn’t bode well for a slate of big tech earnings next week – where we’ll hear from Microsoft, Meta, Amazon and Apple.
