In reply to Pesda potato:
The trouble is that the obvious solution is technology, something daring and new (although i'm liking Johnny Dawes's no hands climbing and think there should be an addition to the Rockfax app for it) or a person that climbs really really hard, i'm not sure that's it though.
I think the future is more about the culture of climbing, becoming more focused on the joy and experience of it and caring more and more about conservation.
We live in a world where more and more people are climbing, gear companies want to sell more stuff and pro athletes want to be sponsored. This is great, climbing is a really life enhancing activity (sport?), spangly light gear is nice and having athletes to inspire people is pretty cool. but I can't help but think that the next logical advance is a shift to people becoming more and more interested in adventure, the mental (and spiritual) sides of climbing, our inter-relationship to the landscape (and it's conservation) and there being a focus in both climbing and wider media in the joy and experience of things. The great gear and increased skills of young climbers is something which allows us the luxury of this. For a glimpse into what i'm trying to say have a read of old copies of 'the surfer's path', it's mostly about people on bits of plastic in the sea with odd bits about about saving sealife, saying no to sewage, etc, doesn't sound amazing but it's a beautiful and inspiring magazine to read.
The other big questions are how will we adjust to the likely increases in costs of travel and and what is the future environmental capacity of climbing in the UK. In the future will cheap RyanAir flights still be a feasible option for a quick climbing holiday and how do we respond to the challenge of a country with a much greater population, and more people climbing?
The other cultural aspect is that maybe in the UK climbers should be nicer. There are loads of nice climbers out there, but I think as a community we need to try harder. On this forum last week there was a chap who innocently asked what a baselayer was and the replies weren't what you'd expect from a group of people who should be welcoming someone new to the outdoors into their world and acting as ambassadors; this could have been that person's one and lasting experience of rock climbers.
I think in the future it would be great if everyone (i.e. every climber/mountaineer/hillwalker etc) also got more involved with the world of conservation. If we care and love the amazing places we visit we need to not only celebrate this in books/websites/magazine, but we need to integrate ourselves more with the world of conservation, go out and join local conservation groups and whilst its not that we don't do this already, I think it has to be at the very core of what it is to be involved in climbing or mountain walking.
