How Has Chess Changed With the Advancement of Super Strong Engines?

M: I think i feel like it has changed over the years, but at the same time, in some ways, i have calcified two. When i was around 27 hundred, i played every opening onther sun. Now, as i've gotten older, i can't do that. And then generally, also with ingines a, i feel like a lot of stuff that i used to believe was playable, i just don't like, you know, the nidorf. Sppose sppose if you'll see them go and start playing one or two openings? M says he feels optimism is very important for chess players.
