I agree that it isn't opinion-based, but part of it is off-topic.
On-topic: a question similar to "what areas of EE overlap with quantum computing?" This is for sure a question about electrical engineering.
Off-topic: a question similar to "is anyone doing research on topic x?" Which isn't a question about EE but a question about what on-going research programs that might exist across the world.
However, it is not uncommon that on-topic questions contain various derailing into off-topic matters. Like a schematic design review question (on-topic) also containing part recommendations (off-topic). Generally these can be edited into shape or we can just ignore the off-topic part of it, as long as most of the question is on-topic.
In this specific case I think it's on-topic enough for us to leave it alone. I've cast a re-open vote. However, big picture questions that are cross-disciplinary (Like EE, chemistry, physics all at once etc) might be more suitable for https://engineering.stackexchange.com. One could ask on their meta if they think questions like this are more suited there.
