it has two possible meanings depending on form it could mean what forms as in life forms, in which case take means carry or bring or, if form means shape, take would mean to manifest as so you need context

In this context, the word TAKE refers to form or state or capability. Therefore, "... I wonder what forms these technologies take" means the speaker is wondering about the shape or form or state of the alien's technological advancements.
