I have a boob job. what will happen in 30 years?

Many possibilities: Hopefully your improved appearance will allow the attraction of a kind and sympathetic partner who will love you no matter what the state of your chest implants can migrate, rupture, or develop a hard outer capsule. Some of these may require removal or resurgery of some type. It sounds like all is ok for now, but if there is any difficulty down the road, consult a plastic surgeon.

Breast Augmentation: Breast implants are designed to last a long time, but like all man made devices they are not perfect. Depending on their size, the quality of your skin & tissues, fluctuations in your weight and other factors like pregnancy & breastfeeding, they may require some "touching up" after that many years. Other problems like capsular contracture or rupture may also require them to be replaced.

Good question: The same could be asked of any breasts in 30 years. The only thing that can be guaranteed is change. Breast implants are not lifetime devices, which means they could fail (leak). Gravity will also have it effects, as does the normal changes in the skin and breast tissue that occur with age. Enjoy the results now, but be prepared to maintain them later too.

Much can change: Just like for any woman, the breasts change over time, whether they have implants or not. With implants, tissue stretch, hardening, and implant leakage and the need for implant replacement are additional concerns.
