Is it not at least equally likely that the present is crazy, and the past was wise?
No, it is not. Knowledge is generally cumulative, although there are occasional setbacks
There are frequent major setbacks
If it is not "at least equally likely", it is still quite likely - particularly in matters influenced by politics, where knowledge, for obvious reasons, does not accumulate.
To defend the present, one has to argue truth, not cite today's authorities. One has to compare today's authorities with the evidence on which their claims are supposedly based. That the official truth about the past is a lie reveals social decay, just as that the official truth about the Soviet harvest was a lie revealed that communes do not work.
The way the wind is blowing, future generations living in hovels may well be as amazed by the moon landing as we are amazed by the Antikythera mechanism, as political lies spill over into bureaucratic lies, producing irreproducible results in science.
Today is Ada Lovelace Day, when STEM enthusiasts highlight the work of modern and historical women scientists, engineers, and mathematicians. If you run a blog, you may want to participate by posting about a woman in a STEM field whom you admire. But I'd love to have people share women scientists/mathematicians/authors in the comments that they think we could all stand to read more about.
