  Galaxy-scale strong lensing is a powerful tool in Astrophysics and Cosmology,
enabling studies of massive galaxies' internal structure, their formation and
evolution, stellar initial mass function, and cosmological parameters. In this
conference proceeding, we highlight key findings from the past decade in
astrophysical applications of strong lensing at the galaxy scale. We then
briefly summarize the present status of discovery and analyses of new samples
from recent or ongoing surveys. Finally, we offer insights into anticipated
developments in the upcoming era of big data shaping the future of this field,
thanks to the Rubin, Euclid, and Roman observatories.
