Motivating Gen-Z in the workplace

Millennial boss here. Legitimately confused on how to motivate Gen-Z to be excellent at their jobs. They are mostly intelligent and capable but they seem to not care if they are accurate, efficient, or subject matter experts.

Sometimes it feels like they think they are baristas at starbucks - like, "here is your effing coffee, I have other orders bye". Are they in aerospace for the check and the clout? They don't seem to care what the project is as long as its glorified. What happened to geeking out and solving a problem with the BEST solution because its fun?

We've made a lot of progress in terms of office etiquette, general camaraderie, teamwork etc. (not easy!) however, they seem destined to NEVER be anywhere as close to what we were at their same age and they don't seem bothered by that at all.

Can humanity survive if the future is just people being mid? Is it just post-covid reality? Advice, suggestions, and feedback welcome.
