I wouldn't say you're worried for no reason, but software is an outlier: it requires very little equipment to build. You could literally write software anywhere in the world as long as you have a computer, and as a byproduct, an Internet connection. If you're sufficiently motivated, you'll always be able to find work, either as an employee, or as an independent consultant.
