Group 1 - The core viewpoint of the article emphasizes that investors' attitudes towards AI have shifted from long-term speculative visions reminiscent of the 1990s to a focus on immediate, quantifiable profit performance [1] - Ben Snider, the incoming head of Goldman Sachs' U.S. equity business, notes that the current market is more cautious, learning from past experiences such as the internet bubble, which led to inflated valuations [1] - The market's current focus on sectors like semiconductors, hyperscale data centers, and utilities reflects this more pragmatic approach to investment [1] Group 2 - Snider points out that speculative activities in the market have significantly cooled compared to the internet bubble era [2] - Goldman Sachs has established a "speculative trading indicator" to measure the proportion of trading activity from loss-making companies, small-cap stocks, or overvalued stocks, indicating that current speculation levels are much lower than 25 years ago and even below the market frenzy of 2021 [2] - Snider describes the current investment environment as potentially the "least frenzied yet often labeled as a bubble" in modern history [2]
