I an addition to having to communicate with a lot of stakeholders, keep coding. I have seen plenty of architects that lost touch with the technical side after a while and turned into major obstacles. If they are politically savvy they are the go to guys for management but their actual contribution is negative because they often push the wrong designs and suppress ideas from people who work on the code and have a handle on how things really work.

In my view as an architect you need stay a top notch coder.
