Second Life has potential benefits for businesses but also drawbacks that limit its usefulness for mainstream business activities. While some major companies have used it for advertising and experimenting with new ideas, technical issues like latency, crashes, and security risks make it difficult to rely on for important tasks. The virtual currency also raises questions, as people spend real money on virtual goods. Overall, while Second Life opens new opportunities, real-world interactions are still necessary for things like interviews and education due to concerns about technical limitations, security, and the lack of in-person impressions.
