You can find a lot of opinions on the internet.

You can also easily find 5 links where people claim that the earth is
flat.

Something being said by some random person on the internet provides
very little indication that it is correct.

The above links are not particular convincing. And if you like then
I can provide some explanation.

If you look at where the industry is actually moving with new languages
and changes to old languages and modern style of old languages, then
the trend in my eyes are:

business application languages:
* multi paradigm (OO, G and FP)
* preference for interface inheritance over implementation inheritance
* GC
* static strong typed with type inference
* VM based

platform languages:
* multi paradigm (P, FP, G and light OO)
* focus concurrency
* native

script languages:
* multi paradigm (OO, P, PT and FP)
* dynamic typed
* VM based

No sign that OO is going away.

But OO today is a bit different than it was 25 years ago.
