The idea isn't just to remain dynamic, but to allow for new products and services to be developed despite posing a threat to the company's main cash cow.
So Lab126 was completely independent from most of Amazon, including being based in the Bay Area vs. Seattle. This allowed the to develop a product that went directly against the main cash cow at the time (selling physical books) and make it to market.
Microsoft had one as well, but would always fail because the existing businesses heads held too much power, and would always kill the products. Just take a look at the history of the Surface.
I know this from all the com.lab126 Java packages in the firmware :)
Or, at least, the technology might have been obvious (they did have a hand in developing digital cameras), but the idea that they should bet big on the new technology eventually replacing them evidently wasn't obvious.

There's other benefits. Such-as institutional knowledge that can be used to determine where to invest VC money / acquisitions.
Or the strategic part where you leverage R&D spend to sign quid pro quo contracts...who's earnings might boost some quarterly earning metric.
There are rare exceptions in anything - but the existance of lottery winners does not mean the expected payout of a lottery ticket is positive.
Bell Labs used its monopoly profits to fund research - which was good for research, but no so much for Bell.
If we consider AT&T as Bells successor, it only allowed Bell to stay relevant. Still, AT&T now is nowhere close to Bell it is heyday. Same for Xerow now. Research doesn't pay as much as companies seems to think.
While google position in online advertising is as close to a monopoly as legally possible, it will not change the structure of the incentives. The odds are against them.
But maybe they do not aim for the kind of success they claim they will have, and only want to stay relevant, like Microsoft is now. That is more possible, even if it will be hard to pull.
Personally, I think most R&D money that companies like Microsoft (or Google) have sunk into internal R&D could have had much better uses. But it's not my money! And eventually white elephants get butchered for the meat, so no big loss there.
Some companies are constantly researching ways to improve their products. Facebook, Amazon, Google, Microsoft, and Apple come to mind.
Some companies are constantly researching for new ways to find their resources. Every oil company comes to mind.
I think your claim is way, way off.
Ex: tablets for Microsoft in 1994. Google driving cars.
The "current business line" of Google was Search. Full stop.
Some people thought it was absurd when Google started doing email, or smartphone OSs, or browsers...
I could go on and on.
Microsoft doing gaming consoles. Amazon doing web services rather than online storefront...
Too bad it has never worked too well for any other big company, for structural reasons ("Internal incubators")
