It's not vaguely adjacent, the actual foundations of that research were directly publicly funded and wouldn't be possible without it - the author is not talking about how their PageRank algorithm got funded nor money that Google received.
Do you have a reference here, or are you just going to continue to baldly state it as a fact? I’m looking at “Attention is All You Need” and don’t see any grant numbers or anything like that.
When I see that paper, I see 32 references at the end. I'm not opening each one of those but there is probably significant grant funding behind that exploratory research. When you actually look at their results its only about a half page. Most of that document is merely providing background and context out of the academic literature. Conclusion is literally just a 1 sentence paragraph, followed by a 2 sentence paragraph, followed by a 3 sentence paragraph, then a link to the git repo.
