I think you're being a bit harsh, (it's in a far, far, far better place than Starfield), but as someone who enjoys civ7 - I think this quote is very much true at this point. If they want to bring new players in they'll need to start addressing some of the issues which turned them off the game. The era system (and its attendant baggage like civ switching) really is turning into a bit of a millstone around the game's neck.
Trouble is Civ7's more controversial systems are so interconnected that there'll be a snowball effect once they start any changes... And I think any changes would have to be game modes/equivalent of mods, so a version that still has eras can still be played, which makes it likely that you fragment the audience. I hope firaxis have it in them to do something dramatic, but I don't think it will be painless if they do...
