People can and do change all the time. Humans instinctively stick with what they know, but in reality most people could be more efficient by learning things outside of their comfort zone. The few people that do this are rewrded greatly by having multiple strings to their bow, and being adaptive to many environments.

Those that stick with they know are super efficient in their own environment, but take them out of that and they invariably complain that they could be better if they had the tools they know.
