Perl 6: The upcoming Perl 6 means I'll have to invest a lot of time to understand how it works.

No more than the usual 'I better check out this new stuff' while you continue to do Perl 5.

Pv6: It was promoted on the news & published on many websites that people will start to acquire/use IPv6 which means I'll have to invest more time to understand how it works OR I'll have no idea about networking.

IPv6 is at a level that 99% of us won't ever need to worry about.

HTML5: The new HTML 5 Also means I'll have to set down and start learning about the new tags, features ...etc.

So you expand your knowledge about how the new tags work. That doesn't sound like a bad thing.

Power Shell: This one might be old, but I used to use windows wizards, GUI interfaces but using the Power Shell seems to be easier and a good way to automate things so here's a new scripting experience you'll have to acquire too.

Go ahead and use the new tool if you like; I'm perfectly happy with gvim and a pile of xterm windows.

Although I am not too old, but I already feel outdated.

Pffffft. Buddy, I finished high school in 1975. I grew up with teletypes, 110 baud modem, paper tape and punch cards. In this business you learn and grow, or you get into some other business. :)

I believe a lot of the stuff you're concerned about is new features on an old platform. The old stuff isn't (much) going to disappear.
