\begin{equation}  N \approx 5\, f_l \, f_i \, f_c \, L  \end{equation}\label{Drake_simplified}  The interesting fact about this compact version of the Drake equation is that it only contains factors dealing with the emergence of life itself. Broadly speaking astrophysics has answered the question "Is the Universe likely to provide the right environment for life as we know it ?" with a big "yes!".   Time to deal with astrobiology.
