The theses of positivism are relevant even now, even very relevant, Auguste Comte, the founder of sociology and positivism, considered sociology, and indeed philosophy, the most positive science, which indicates the path of development to society and, in his words, the stage of positive thinking, i.e. ... the stage of highly organized thinking is the path of the future.
For a start, it should be noted that philosophy penetrates into science with some delay. That is, perhaps that methodology is already being developed or developed (I do not follow the current processes in this area), which will become dominant in science, but in 20 years Popper became a common place not immediately after the publication of his main work, it takes time for an idea It spread, gained popularity, took root and began to be taught at universities.
Further, the sociology of science is now very actively developing, which (like very much in modern sociology) grows from Foucault and this view is very different from the post-positivist, but it is rather a descriptive model of the scientific community, they do not try to dictate "the right way", and if they suddenly do try, it is somewhat reminiscent of Feyerabend.
