Not scientists; engineers. From the beginning essentially all enthusiasm for the idea has been driven by engineers.

Warp drive is a case where the usual relationship between physicists and engineers is flipped: we physicists have always agreed that warp drive is possible in theory, but basically impossible to realize in practice. Yet it's the engineers who are interested in it!

Only in the sense that it's possible solution for Einstein's field equations if you assume the existence of negative mass.

It's not theoretically possible without completely new physics. You must first discover multiple Nobel prices worth of fundamental physics before even thinking about engineering.
