Each of us (Software engineers) start our career as fresher in some company. For the first few years we explore and learn new things. Next few years we do some projects on javaj2ee .NET php etc etc and after some 10 -15 years we become managers of some kind and finally MS office becomes our primary tool.
This the observation i have made in most IT companies. Excepting your comments and observations on the same.
I think it is true that as you move into management - if that is your path - you become necessarily removed from direct use of certain hard-skills - ie: the programming languages. MS Office may become a more prevalent tool - but the tool is simply a mechanism for communicating. The real skill of management is recognizing resources, keeping teams on track, conveying the business case and need to the technology team, etc.
This, by the way, is true when you are a programmer too. Meaning, the programming language and technology is simply a tool that you use to solve the business challenge. The closer you get to understanding the business case for your technology - to head the user's off at the pass and know/see what they need even prior to them asking - that is what will make you a better/more valuable I.T. professional.
