The rise of artificial intelligence (AI) ignited the investment enthusiasm in the technology sector last year, making AI companies a hot target for investors. Despite concerns about the security and privacy of ChatGPT and other AI chatbots, investors generally hold an optimistic view on AI stocks. However, is this optimistic expectation realistic? Sam Altman, the CEO of OpenAI, has raised doubts. He believes that although AI has tremendous potential, people may have overestimated the capabilities of AI. At the World Economic Forum held in Davos, Switzerland, Altman downplayed the long-term impact of AI. He believes that the changes brought by AI to the world may be much smaller than people's expectations, and the same goes for changes in jobs. Despite a study by the International Monetary Fund suggesting that AI may affect 40% of jobs worldwide, Altman is skeptical of such predictions. He warns investors and the public not to have excessive expectations to avoid eventual disappointment. Microsoft, Palantir Technologies, and C3.ai were AI stocks that received significant attention in the past year. Microsoft's stock price rose by 57%, and its AI-driven Copilot feature in the Office products attracted market attention. Palantir launched an AI platform and saw demand growth, but its growth rate has not taken off yet. C3.ai provides AI analytics services to enterprises, and its stock price rose by 157% last year, although it experienced a decline in the second half of the year. Investors should approach AI stocks with caution and avoid excessive expectations. Although AI has long-term potential, it is currently unclear what specific impact it will have on jobs and businesses. Investors should focus on the actual financial condition of companies, their current performance, and whether the projected growth is realized, rather than blindly following the hype. Altman's warning reminds us that when investing in AI stocks, we need to analyze rationally and make cautious decisions, instead of blindly following the trend. Only by thoroughly understanding and evaluating the actual performance and potential of companies can we make wise investment decisions.
