Is there discrimination at the average company against 35+ candidates? Yes.

Is it because the candidates don’t know the latest languages and frameworks? Sometimes, not always.

Is it because “fresh grads” have “energy” or something? Almost certainly not. What does that even mean?

Is it negated by the comments here like “oh there are 70-year-olds doing programmig where I work!”? No, that’s just an anecdote, not statistically relevant.
