"It's embarrassing to use jQuery" - Do you agree?

I was working on a simple landing page for one of our projects and suddenly my boss, who happens to be a CTO, tells me not to use jQuery. He thinks it will be embarrassing when other developers discover we still use jQuery in 2019.

In my opinion, it's completely OK to use jQuery in simple websites rather than converting each project to React or Vue powered. Do you agree with this?
