College professor and former AP scorer, here.
It depends. First of all, which colleges is your child looking at, how much course credit do they offer for a high score on the AP exam, and how likely is your child to actually achieve that score? Assuming they take a sufficient number of AP courses and do well in them, there is often a real opportunity to shave a semester or a year off of a college degree, which is a pretty significant benefit if the student is struggling to pay for college, or if it frees them up to do something else beneficial with the credits and time they save (double major, semester abroad, etc.)
On the other hand, there are plenty of situations where that isn’t as beneficial as you might think. For example, students in my university’s residential Honors program generally get a scholarship package that covers a full four years; there’s no reason for them to WANT to complete their degree faster, and having AP / dual enrollment credit for too many of our gen ed courses can actually cause complications, because they are expected to take a number of those classes as a cohort. Usually, our answer is “too bad, we know you already have credit for World History I, but you’re taking it again regardless,” because it’s a small enough program that giving them a choice isn’t practical, and because we figure Honors World History I at the college level, with a different instructor who emphasizes different stuff, is likely to be different enough from their high-school version that they won’t get bored. But they are often unhappy that they “wasted” time taking the AP course in high school.
At the other end of the achievement scale, there are schools where too many students are pushed into AP regardless of interest or ability level, the quality of the course is correspondingly low, and it’s a waste of everyone’s time. In my AP exam-scoring days, we sometimes saw whole batches of essays, evidently from a single school, where it was clear NOBODY would be earning a passing grade. I don’t know anything about your kid’s school, but I would say if they’re encouraging 10th graders to load up on AP, that’s a bit of a red flag. 10th grade is young, and most 15-year-olds are not really intellectually ready for college-level coursework, so unless this is a private / magnet school with selective admissions, it’s likely to end up being an AP course in name only.
There are also schools, and students, where AP is clearly the better option just for its own sake, regardless of the potential to earn college credit. If your kid has a passion for a particular subject and WANTS more advanced coursework, it’s a no-brainer. If the school reserves its best teachers for those courses, it’s also pretty much a no-brainer (with the caveat that “best” doesn’t always mean best for any given student, and that being in a demanding class you have no interest in is a recipe for disaster).
Finally: what does your child want to do? IMO, if they’re old enough for college-level coursework, they are old enough to make decisions about their education for themselves.
