Might anyone be able to comment on his employment in all these years?<p>Every time I've come across this article it's seemed to me that the work he's done, whilst notable, is an entirely reasonable and very achievable <i>amount</i> to have completed over the course of the at least 20 years that he has been developing.<p>If he has held a full-time job that takes away the majority of his time or something similar (as many here have) then I could understand these codebases being particularly notably huge. Otherwise, as has been commented by others here, this level of productivity, whilst admirable, seems to strike me as similar to many, many programmers working around the world - in their cases simply behind closed doors, instead and not working on their pet projects, but on those chosen by their employers.<p>Thoughts?
