Board games wont die, there's nothing quite like working across the table with a good friend and a beverage and die in your hands....there will always be people who do it.
Some of my favorite boardgames don't even have dice, look at Acquire.
While I understand what your saying, there are really two seperate discussions here. The demise of board wargames and the demise of ALL boardgames.
First, about trivia boardgames:
If you were to ask someone even just 5 years ago this question in regards to trivia games they would tell you something similiar to what you said above. But the fact today is, when people play Scene-It they still have a beverage in hand. They are still laughing and socializing. And possibly even more so. For those I have played it with (many who wouldn't even play trivia style games before) they find it much much more enjoyable seeing the onscreen clips and interactive questions and so forth, especially those that otherwise didn't get as much enjoyment out of trivia games because they knew less answers. Now its more fun for everyone all around.
I've yet to here someone argue why Scene-IT and further enhancements won't achieve replacing "board" trivia games.
The point is, its just too hard for most people to imagine doing things other than the ways we are already so accustomed too. After the fact, its much like an "of course so". But beforehand its always total skepticism.
PC's vs Boargames:
I wouldn't suggest that PC's alone would kill boardgaming. But technology, in general, well could.
Perhaps too though you'd have to define what a boardgame actually is. Does it have to have a cardboard "board" and dice you can throw across the room? How about an LCD coffee table that displays a monopoly board? You can even set your drink on it just like the one thats just Oak sitting in front of the TV with a monopoly board on it. Alright so you still want to "touch" something else. How about a special box you throw your dice in that has one of those laser scanners in it to read them? You could even hook that up to a PC for die-rolling in any game that decided to support it.
If the "physical nature" alone is what defines a boardgame then wouldn't a game with a lot of "gear" that you touch qualify? Couldn't "Duck Hunt" be said to be the first game like this?
You can hook an endless number of input/output devices up to computers, tvs and dvd players. Notice how much technology has improved in the last 15 years but we still mostly use the same input devices (keyboard, mouse) and output devices (monitor,printer). These are the things that are finally going to start changing and one of the main things that will improve the overall experience.
In the Future:
How bout the VRglove of Black & White fame hooked up to your TV for any of the games where you make motions? Someone is bound to find a way to integrate devices such as that to make social games a whole lot more fun than they even are today. Then playing those games without it will seem similiar to now playing a trivia game without the dvd content, disappointing and even outright boring to some.
I will likely never play an old-school trivia game again. If I play an "old-school" complex board wargame it will be out of nastolgia and not because I prefer it. I do still play Axis & Allies, RISK, Acquire, Monopoly, and a few other boardgames because, to date, technology has not yet achieved the things I've said it will.
Do you really think in the year 2105 people will still play games with cardboard (plastic or whatever) pieces? If so it would probably be as a novelty item (ie. an expensively custom carved chess set you'd rather not play with anyway). A "museum piece" if you will.
At some point in time, the demise is inevitable. It only remains to be seen whether that time is 10 years out or 100.
