"overcomes error snowball effect from manipulating thousands light variables at once using diffractive neural network... light bounces through cavity hitting patterned surfaces, each reflection gradually reshapes/ nudges light into desired pattern... single beam simultaneously carries multiple independent information channels with near perfect alignment, utilizing 1 million microscopic self learning/ adjusting mirror grid that can move 1,000X/ second... medical imaging, vastly increased internet speeds"
