I don't necessarily think your Aspergers gets worse as you get older, or better for that matter. The things you're doing and the skills you've learned can either help you manage your condition, or make things go out of control. Stress fluctuates, and stress/anxiety makes our coping mechanisms less effective. So, sometimes, it looks like we're getting worse as we get older because there are life changes that are very stressful... spouse, kids, home, job, etc. The longer you work, the more "upper level" you are generally expected to become, so you get promoted into a job that has more social interaction... eeeek stress and failure!
One thing I noticed from my own experience... stress and anxiety is cumulative. Just because you dealt with that crazy thing doesn't mean that you don't have a scar. The accumulation can happen so quietly and slowly that we don't notice it, and the BOOM we have a meltdown. If you have enough meltdowns you can actually develop a severe aversion to those sorts of situations (i.e. anxiety disorder). You become hypersensitized and can develop Complex PTSD. I think this can be avoided if you catch the situation early enough... like you realizing that your job is related to your increase in symptoms. If you can make a change before you have a blowout I think it does you less damage in the long run. If you limit the amount of times you completely lose it, you might be able to spare yourself from completely divorcing yourself from the world.
Of course, there is nothing wrong with completely divorcing yourself from the outside world (as much as is reasonable of course). But you should only do that if it's what you really want, not be forced into it because you can't cope anymore.
