Definitely. There's the old line about being indistinguishable from magic, and I think it very much applies here. Fly-by-wire and algorithmic control of aircraft allows for some incredible feats of aerobatics that are hard for humans to imagine performing. We knew this I think over a decade ago now with MIT's demonstrations of quadcopters performing sweet tricks, but for various reasons (that, personal opinion here, come down mostly to the near complete capture of military R&D by a small group of defense contractors with little motivation to perform actual R&D) we haven't really tried that hard to apply this sort of technology to military aircraft. Some of the UAP documents from ODNI have, in my reading, supported this type of hypothesis. The key phrase "unusual flight characteristics or performance capabilities" in one ODNI report sounds to me like ODNI thinks they're seeing behavior that is inconsistent with our current aerospace technology but not inconsistent with physics---in other words, someone knows how to do things that we don't. It could be aliens, but...

If we assume that these orbs and other military UAP reports reflect genuine flying objects (and on the balance of the evidence I think they do), my money would be on China or Russia having invested a lot of time and effort into computational control of unmanned aircraft, probably integrating hypersonic aerodynamic research we know both countries have been performing (and have almost certainly surpassed the US on). The result, I think it's pretty reasonable to imagine, could be compact unmanned aircraft capable of some really extreme maneuvers. There are plenty of open questions with this theory, like power sources, but I feel like it's in the right balance of pushing the bounds of the possible without requiring off-planet intervention. Remember that the US fielded both low-radar-profile aircraft and extremely high altitude aircraft with a great deal of secrecy. These would have been quite UFO-like to the Soviet Union, but had perfectly rational explanations... just explanations that involved at least a decade of advanced R&D performed in secret.

More to the point, though, I think we have to be really careful with this "extreme flight characteristics means aliens" line of thinking. It's exactly what got us into the situation where claims of UAPs were viewed with such skepticism that they were suppressed within the military. We have to admit aliens as a possibility, but China is a whole lot closer, and we know that she has a sophisticated and well-supplied military R&D program. Decades of research ought to have gotten them something, and it would probably look pretty weird to those of us not in the loop.

Yeah. I'm sure it due to incentives in that academia industry. Publish or perish means publish in journals with established credibility.

But it's good that they don't plan to release findings through news media.
