AI bubble becomes the focus of public opinion again? Economists warn: Nvidia might be the new Cisco

```htmlGolden Ten Data June 5｜As NVIDIA once again becomes the center of market attention, it has sparked renewed debate: Can the rapid development of artificial intelligence (AI) support the expectations currently reflected in tech stocks? NVIDIA rose to prominence because of AI—will it end up like Cisco did in the past, heading toward a crash? Dario Perkins, an economist at the macroeconomic research firm TS Lombard, noted in his latest report that history tells us we should act with caution. During the internet boom of the late 1990s, Cisco became one of Wall Street's biggest winners, as investors bet that the company would benefit from the rapid expansion of online infrastructure. Although the internet eventually transformed the global economy, Cisco's profits took much longer to reach the lofty expectations reflected in its share price. "Perhaps NVIDIA is the new Cisco," Perkins wrote; even if a company is highly profitable and holds significant strategic importance, investors can still be disappointed if its growth does not keep pace with market expectations.```
