Lack of consequences is so often forgotten.
Let me rant here a bit because I really am sick of how all of this can work.
Let's look at the newest example from gaming, our beloved Concord. Sony sunk a fuck ton of cash for a game that has absolutely nothing new in the first person hero shooter genre, this game did nothing new, costed 40$ while most of the competition is free to play and while most hero shooters play fast with dynamic movement or are slower more tactics based, concord did neither, it was slow and as far as I know it didn't have that much team tactics.
Concord shouldn't have left the idea phase, whatsoever writing it down on paper with concept art since there was nothing there to put down on paper.
And yet it was made, costed (according to Wikipedia) $400 million and made maybe one milion USD (before the mass refund).
Did someone uptop that actually decided to make this crap get fired? No, of course not. Sony only shut down the developer studio behind the game. People lost jobs in a highly competitive job market because thier employers were absolutely braindead, these people weren't the designers of this game, they didn't greenlight a empty shell of an idea, they just coded what they were told to. While the higher-ups suffer no consequences, hell, the 400 Million won't be even a dent it Sony's yearly profit of 34 Billion.
When ice forms, it traps small airpockets in it, so we take samples of ice from the polar circles kilometres deep, date it, crush it to release the air pockets and measure the air contents. Then we can see how different the CO2 amounts were to now.
