You might scoff at the idea that someone who designs computer programs should be described as an 'architect,' but the difference between a computer programmer and a software architect is the same as the difference between a builder and a structural architect. The former is capable of putting the pieces of a product together or fixing it when it breaks, but the latter had the vision to design it in the first place.
Think about all the software you work with every day. Someone had to design the browser you're using to read this webpage. Someone built the framework this webpage is hosted on. Your word processor, your email client - all the work of software architects! A degree in computer science or software engineering will get your foot in the door, and you'll also need to keep yourself up-to-date with the latest technology and software changes. Old knowledge is useless knowledge in the software game!
