I object to the framing of your question, on basically every level.
Among "many high profile papers or projects" obviously comparable to AlphaGo, (or more importantly AlphZero), is Watson, because it was the first computer system to beat human supremacy at Jeapardy. From the Wikipedia page on Watson:
"Current and future applications:
IBM Watson Group
Each with a whole section. Natural language processing has been behind the wave of voice-input devices that dominate tech company agendas.
Look at Deep Mind the company that developed AlphaGo. They list their algorithms (using the same weighted monte carlo trees & conformal neural nets as AlphaGo), as improving Google's: data centre cooling, recommendation engines, and adaptive battery use & brightness as part of the Android operating system since 2018. There are massive applications to healthcare for things like evaluating scans. And for understanding protein folding, a giant new field in it's own right that could open up world-change catalytic enzymes, for things like crop-waste to fuel.
This is all long after the giant leaps they made with 2D image processing, and now being made on 3D+ info exactly using conformal neural networks. I am really excited by applications of AI to understanding the physics of higher dimensional spaces.
You didn't ask for a survey of the field so I won't go on. No offence but, you haven't done the most basic research, like reading about Deep Mind, and it sounds like you haven't even heard of Watson.
Artificial general intelligence is likely to dominate the future of life on Earth, as the key technology of at least the next century. Either as independent beings, or hybrids with humans using interfaces like Neuralink, a new kind of being/s will supplant (unmodified) humans - in philosophy that's discussed as transhumanism. And the supremacy issue has been called 'the gorilla problem' by Stuart Russell & others by analogy to how gorillas have lost self-determination/autonomy to humans.
On 'blue sky' research I'd say quantum computing is at the level of usefulness of AI maybe 40 years ago. It's notable no one is saying, what's the point of researching that - but actual applications are substantially less clear than for AI 40 years ago. There are only 2 quantum algorithms, and only 1 that's practical. As a current application it's pretty much just cryptography, and clear unique one's for the future I have only heard of evolutionary algorithms. But the point is, it will be an accelerating technology, wherever it gets applied it will have compound impacts . There is a known human cognitive inability to grasp the effect of things like compound interest, and exponential and logarithmic change. But in the long run, really nothing else matters as much.
So we already have huge applications, this quickly. Certain technologies we know will define the future, because they have cumulative compound effects. And the last point I'd make, is from game theory. In WW2 & the Cold War, Nazis & Soviets respectively had the best tanks, planes, and conventional military advantages, at the start. But looking at how radar, decryption, ICBMs, space-based warfare, developed & the costs associated, it now looks inevitable they would lose. And it was the mix of relatively meritocratic universities (Nazis lost all Jews including many who joined the Manhattan Project, USSR lost many brilliant minds to purges & politics), and to the finances of the bigger trade network. In hot or cold wars, or just geopolitics, we already know AI will be the major tool of propaganda, as modern Russia is proving, and it will control increasingly autonomous drones as USA is proving. Having the infrastructure and the minds for AI, even if not currently doing it, could likely be the deciding factor in winning, or stopping, wars of the future. So it will decide who's politics, who's world view, who's philosophy, shapes our future.
