If you're going by the use of Golden and Silver age in comics that denotes a time period rather than a period of exceptional quality, then yes, the Golden Age of gaming is well and truly over.
You could make a case for it being from 1970 -1990, with 1990-2010 being the Silver age. Though that would put the Megadrive and Snes in different eras, so likely 1972-1992 is a better time frame for the Golden age of gaming. From Pong to the release of the 16 bit consoles.
In terms of quality, I'd argue gaming has never been better in the present day after over 35 of gaming for me, if you know where to look and mostly avoid microtransactions, there's still great gaming to be had.
I'm currently switching between Dragon Quest Builders 2 - the best Minecraft type game I've ever played and my retroactive game of 2019 as I only got it this year, even beating RE2 Remake for me, along with Monster Hunter Iceborne, Capcom Street Fighter Classics on Steam and various games on my Snes mini.
It's telling that the 2D offerings on the Snes mini have aged a LOT better than most early 3D games did, it's testament to just how good Mario 64 was that it can still be speedrun today, but many other games from that genre aged horribly.
Even some games from the just a few years back can look very dated, whereas Super Mario World will still be playable as it is, as a high end example of 2D gaming in 1000 years time. Some of those muddy old 3D PS1 and N64 games are going to look like absolute rubbish in terms of looks and janky 3D gameplay, as many do even today.
So I'm still loving gaming, I've still got access to all my old games as well as many great new games that will continue to be released.
In terms of 3D gaming, the best is still yet to come as graphics approach photo realism, innovating graphics standards can level off like they did at the end of the 2D era and focus can go back on game play and AI rather than chasing graphics all the time.
