This is a fantastic time to be entering the business world, because business is going to change more in the next 10 years than it has in the last 50.

Gates is emphasizing the accelerating pace of technological and organizational change, arguing that newcomers to business are arriving at a moment of unusual opportunity. The claim implies that long-established practices—how companies communicate, manage information, reach customers, and compete—are being reshaped faster than in previous decades, largely due to computing and networked information. The quote functions as both encouragement and warning: encouragement because rapid change creates openings for new entrants to innovate, and warning because those who rely on past experience alone may be outpaced. It reflects a broader Gates theme that information technology is not merely a tool but a force that rewrites business fundamentals.
