If you look at the sales brochures from cars in the 60’s you had a huge selection of engine choices and the cars all looked different.
Now, you are lucky to have two engine choices and the cars all look the same. Everything has been standardized mostly due to government regulations. Todays cars are faster and better handling but they all look the same like a bar of soap. Who cares?
It is headed that ways in all products. Fewer choices with 1limited options established by the political class.
They are moving the same way in the news and social networks. Only one narrative supported by a selected event with all other viewpoints labeled unsubstantiated and/or hateful.
Even churches have gone that way, God loves everyone and don’t feel bad because we all sin. Any inconvenient verses are wordsmithed away like a Surpreme Court decision on the constitution.
Sorry, if I am a little pessimistic.
