I’ve climbed with 10 year olds and 80 year olds. Ive climbed with people who could climb 8 hours straight and those who can only do a few routes a day. So long as you have a good attitude, climb safely and respect others you will likely fit in fine at your local climbing gym.
A big problem IMO is the generational responsibility of the waste as well. There needs to be decades of planning, monitoring and maintaince to ensure waste sites are safe and secure, this can be done but modern political climates can make it difficult.
