"it's the last programming language I learned. Ever." This implies that you are going to stop learning, that you are not open to learning anything more, and that your ego is such that you think you are above having to learn anything else, having reached the peak of perfection upon which you can gaze down at everyone else as being not as enlightened as you. This is, of course, folly. Just as one who thinks himself the best to rule the kingdom is probably the worst choice for the job, so too the one who thinks himself 100% enlightened is the least likely to actually be considered enlightened by his peers.
