IMO not a threat, but inevitable.
To any that have eyes and a will to look beyond the facade, western civilization is rotten to the core, obsessed with greed, materialism, and false idols.
When the idea that there are more genders than 2, or that driving an EV will "save the planet", the end is IMO near. They are symptoms of a greater malaise that grips the western world, and that malaise is going to see it follow the Greeks, the Romans and all the other once powerful empires into the bin of history.
We may not watch people being ripped apart by lions for entertainment anymore, but we are nations of bread and circuses, just like the Romans at the end of their long decline from power.
There is nothing unusual about it- it's not as though we are the first civilization to fade away, and the progress from power to inconsequence is well known.
Ozymandias
By Percy Bysshe Shelley
I met a traveller from an antique land,
Who said—“Two vast and trunkless legs of stone
Stand in the desert. . . . Near them, on the sand,
Half sunk a shattered visage lies, whose frown,
And wrinkled lip, and sneer of cold command,
Tell that its sculptor well those passions read
Which yet survive, stamped on these lifeless things,
The hand that mocked them, and the heart that fed;
And on the pedestal, these words appear:
My name is Ozymandias, King of Kings;
Look on my Works, ye Mighty, and despair!
Nothing beside remains. Round the decay
Of that colossal Wreck, boundless and bare
The lone and level sands stretch far away.”
