I've been doing this for the better part of twenty years, so the writing is on the wall for me. It will soon be cheaper to hire 2-3 recent CS grads, with their lack of personal responsibilities, ability to work long nights, and affinity for the latest fad technologies (of which I am increasingly wary), than it is to hire me.
But I am not spectacularly skilled, merely competent. My primary usefulness is in feature solicitation and requirements gathering, as I have the weight of experience when it comes to determining what should be focused on, and I know what works and what doesn't, from years of working on various iterations of sites in different business domains.
As I said, the writing is on the wall. I have no desire to manage anyone. I paid my dues and went freelance, just before things got unfavorable, with respect to U.S. health and professional insurance. I don't really have an entrepreneurial spirit except in as much as I would like to work on important (not the same as "hard") problems with amenable people. I am no longer able to just find a client or employer where the people are smarter, because I am nearly a graybeard. I have sowed my wild oats, and my "I am the CEO / principal consultant / technical founder" days are about a decade behind me.
I don't know what to do next. I just don't think I have more than another 7-10 years doing what I do. The President is essentially calling my domestic clients Lügenpresse. No one seems to care about words printed on paper or eInk, or anything on a screen that is longer than this post. The need for complicated features such as a wiki or extensive document management and versioning are going away, as the clientele become more technical and barely need anything beyond a git repo and markdown at the highest level. I feel myself becoming obsolete, and I am ready for the next thing.
