But every now and then you will see <insert some new tool> being compared with a <insert classic tool>. And then told since the <insert some new tool> is a little famous now, its likely to replace the <insert classic tool> and that <quote some irrelevant search engine statistic> actually proves <insert classic tool> is dead and <insert some new tool> is actually going to replace the <insert classic tool> in the future.

Then suddenly expect a stream of tweets, blog posts and forum discussions on how useless <insert classic tool is>.

Please replace <insert classic tool> by "Perl","SQL","Php".

Please replace <insert some new tool> by "Python","Ruby","Tcl","NoSQL","Django"..

Please replace <quote some irrelevant search engine statistic> by Google search stats or Tiobe(Which is the same ,but presented differently metric).

Sometimes a new tool will come along that truly is a huge improvement on previous tools. But, when those previous tools are "classics", it's pretty rare that the "new" tool is truly that much of an improvement.

There's a reason that these things (bash, sed, awk, perl, SQL, Unix/Linux, etc) are still popular and still going. It's because they're time tested, they're well known, and they work.

While it's good to always review your tools & skills... spending lots of time looking at sparkling new things could be better focused on i) getting work done or ii) improving your proficiency with current tools :)
