I disagree. I think cuisine is constantly evolving, that it has always evolved and that it will continue to evolve, based upon new ingredients and technologies becoming available, and upon improvements in food production, transportation and marketing.
Let's apply your suggestion that "Maybe im old fashioned but personally i feel the old recipes have worked this long lets leave them be" to the situation in Europe "The Old World" (or to Asia) in the 15th century just before America "The New World" was discovered by Western culture. (Never mind that it had already been discovered millenia before.)
The discovery of America brought to Europe potatoes, chilis, corn, tomatoes, just to name a few of the most obvious and important crops. What would European cuisine be without those? No tomato sauce with your Italian pasta? (Which BTW the pasta came from Asia.) Speaking of Asia, what would Thai cuisine be without chili peppers? Yeah these are specific examples and you can cook Italian without tomatoes or Thai without chilis...
Speaking about technology, a century ago we were cooking on wood fired stoves or over open pits. Today our ovens and ranges are gas or electric. Today we have the alternative of microwave ovens which work great for some foods. You would give those up?
I think fusion cooking is really interesting, not to replace everything but it's a novel concept. For example I like Thai (style) pizza!
Yeah for sure we don't need bacon flavored potato chips. (Or I don't know, maybe we do.) I look upon this as a Darwinian evolution of survival of the fittest foods. When new recipes, combinations, ingredients, technologies or fusions come up people will try them, and they'll decide what is good and what's not. If it's good more people will cook it or enjoy consuming it at restaurants. If it's not then the fad will fade out as yesterday's bad idea.
I say bring it!
