RNN's are 80's technology at least:
https://en.wikipedia.org/wiki/Recurrent_neural_network#Histo...With neural network use in image recognition (if not facial recognition) being used at least as early as 1983 (I'm not in the field, so just did 5s of research and found something related) - https://ieeexplore.ieee.org/document/6313076
"A recognition with a large-scale network is simulated on a PDP-11/34 minicomputer and is shown to have a great capability for visual pattern recognition. The model consists of nine layers of cells. ..."
another paper from 1990 using neural networks for facial sex identification:

and software facial recognition itself dates to the 60s.
despite what the 'data science and AI and by AI I really only mean the subset of AI referring to ML' hypetrain tells you, these things are not new, the processors are just faster, and the tools are more accessible, which means the relevant application space is larger.
