How does everybody feel that by the year 2050 Whites will be the Minority?

According to the US Census Whites will be 46 percent of the US Population while Hispanics will be the majority with 42 percent Hispanics compared to 14 percent today and 13 percent African Americans and 9 percent Asian Americans. I mean I see alot of Mexicans today but imagine in the year 2050 woooo America will be very different!!! what does everybody think about this???
