I am sorry, but that is quite untrue.
In April 2014, researchers at the Whitehead Institute for Biomedical Research concluded that the Y chromosome is in fact quite stable, and encodes for genotypes even outside of reproductive purposes. Additionally, the Y chromosome itself is used to trace paternal lineages beyond 2000 years ago (and allowing a man to discover from which haplogroup he is descended) remaining as a whole largely unchanged since then. It is stable and essential. Males as a sex will exist for millions of years to come.
It will change over a long period of time, true, but so will the X chromosome. That is merely a reality of evolution. The Y chromosome is not "disappearing".
