  I summarise the concluding remarks I gave at the Multifrequency Behaviour of
High Energy Cosmic Sources - XIII Workshop. That was not a summary talk and was
meant to be provocative. I first give what I think the main message of the
workshop was, then provide some (biased) highlights, touch upon the upcoming
new facilities and the issues of "quantity vs. quality" and productivity in
astronomy, and finally conclude with a look to the future. Astronomers who did
not attend the workshop might still find the first two topics appealing and the
last two thought-provoking.
