In summer, I like sailing lasers on the Ottawa River. Catching the waves from speed boats can give you a real lift; fighting them can be a challenge; and ignoring them can be disastrous. Over three and a half decades in the industry (I recently retired from nortel), I've seen many technology waves - some big, some small, and some over-rated, but always interesting.
Big or small, each wave is accompanied by technology and business challenges and opportunities... unless the technology takes you where you want to go as a business, it has little value.
I love this industry - it's not about making bombs but about helping people communicate. That's why I take every opportunity to evangelize convergence in all its forms, and why I've been writing a column for TMC publications, most recently Internet Telephony, for a decade.
