Hmm, I guess I agree with your critique. But still, the main reason I wanted to post this is because it counters the otherwise black and white perception of the state of things that reading the news has lead me to. IMHO you are overthinking a bit when you see techno optimism as their metric of progress, although this is something that spending time on Lemmy has also made me do.
Honestly I don’t even care when humankind is referred to as ‘Man’. People don’t (want to) get that in this context it is meant inclusively to refer to all humans, and not just physically men. It’s ‘man’ for historical reasons and its interpretation should change with time just like with that of eg. the constitution.
