In the mid 80′s, while fibre optics was still the new and immature technology I attended a telecommunications conference. Compared to today this was the technological stone-age. After almost 25 years two presentations at that conference stand out in my mind to this day. One was delivered by a Japanese technologist. Unfortunately his English was indistinct and in an auditorium sadly impossible to follow. I am sure his topic was interesting but he was just so much hard work that, along with the rest of the audience, my brain shut down for 40 minutes as frustration and boredom set in. Having said that, his English was far better than my Japanese, so good for him for having a go.
