Tim's current position is something any professional developer should reflect upon. Even if the tools or language one currently uses are popular (and growing more so) at the moment, there's a good chance that they will eventually enter into long-term decline, like Perl has. Ruby users may now feel on top of the world, since despite its flaws the Ruby community is vibrant, exciting, and lucrative, but one day we too may be protesting that "Ruby isn't dying", despite all evidence to the contrary. Being honestly aware of the strengths and weaknesses of the tools one uses, and being willing and able to move to other tools if necessary, are attributes that will probably help one have a much happier career.
