Adventure used to be admired, now cynics ridicule it.
It's not only cynics, unfortunately. Just look at the dwindling funding of space exploration in the western world. Fortunately big business(men) is/are picking up where governments are quitting.
There is a backlash evident in the popularity of extreme sports, but I'd say that's a niche and not exactly adventure in the traditional sense.
Then again there is much to be said about unprepared idiots getting lost in high seas once their GPS runs out of batteries, or getting stranded on mountainsides known for avalanches - and it's the tax payer who picks up the bill for the rescue efforts.
