Calling it "slop" is too harsh. It's an era of mediocrity, or an era of "coasting on past achievements." They've been better in the past, but Apple will get the hardware fixed, and return to their expected trajectory. Apple still supports really good engineers, especially in hardware.
The company that seems to be entering the slop era is Google. They've turned directly towards the revenue as the only metric that matters which means content slop is coming. Google search is barely usable: if it weren't the default search engine in my browser toolbar, I probably wouldn't use it at all (in fact, I'm going to change my UI right now to test that hypothesis). Worse, they don't recognize and support engineering excellence inside the company: they've been taking over by the management class.
So Apple will cruise for a while but Google shows signs of rot.
