Do they actually have lots of species which look the same but are impossible to tell apart except for DNA?
That's only the specimens that have been sequenced and archived at BOLD. That doesn't include the various other bee families, notably Halictidae, Colletidae, Melittidae, and others roughly all the "sister groups" in the Apoidea [1].
An example of why is this important? The Africanized honeybee, known perhaps from bad horror movies, is characterized (identified) as a hybrid of two species. It can be more or less aggressive (to the point of killing you if you don't GTFO) depending on then nature of its DNA. Hybridization has blurred the limits of the species in many areas, including in the US. Sequencing specimens is the only way to confidently determine which of the species you have, A (friendly bee honey), AB (grumpy bee honey), or B (deadly bee honey) (gross simplification here, not Mendelian).

You're talking about The Swarm (1978), which is absolutely so-bad-it's-good. Fans of Michael Caine will I think in particular find it rewarding, and I was especially impressed with its frankly prescient treatment of the drawbacks inherent in mass insecticide application given that the ongoing research increasingly points to exactly that as the culprit for pollinators disappearing.
That said, my understanding is that A. m. scutellata x A. mellifera hybrids aren't unusually aggressive in nest defense by the standards of social hymenopterans generally, but only by the standard of the European honeybee (A. mellifera). I can't claim close familiarity with the relevant literature on bee hybrids, but from what I have seen, their nest defense behavior seems roughly comparable in aggressiveness to that of many yellowjacket (Vespula, Dolichovespula) species. On the other hand, a wild bee colony is likely to be one or two orders of magnitude greater in size than a wild yellowjacket colony, which means that a comparable level of aggression in nest defense could pose a significantly greater hazard.
Using the figures from the Wikipedia article [1] and its relevant source [2], it looks like A. m. scutellata x A. mellifera are responsible for an average of around 15 human deaths per year since the introduction of A. m. scutellata into Brazil in 1956. So I don't really see that there's very much to worry over here, in any case.
Are you? They attack rarely (although are thought to have done so fatally a few weeks ago here in NZ) and aren’t even seen usually, but they are close to popular beaches.

Given that the shark attack stats cover a period 25 times as long as that for the bees, wasps, and hornets, I do feel like "considerably" is a fair choice of adjective here.

Probably people die of bee stings more than sharks attacks here in NZ, but those bees certainly aren’t africanised. I suspect most US deaths aren’t all from africanised bees either but that’s going to be hard to prove.
I've also got to say that for the same reason, I don't have a lot of confidence in the 'fungal genomic analysis' thing in particular, because, on the whole, it seems to me to be so easily manipulated.
Some argue that latin binomials should be abandoned, see "Against the naming of fungi":
Russula sanguinea was described from a European mushroom and therefore probably isn't here in North America at all. The name has been applied to many red Russula in N. A. adding to the confusion. Out west where it may be sorted it is being called Russula rhodocephala which itself is a lookalike for Russula americana but under different trees according to Danny Miller here [1]. Mushroomexpert's Kuo and Mycoquebec say that a lookalike under oaks in the east is Russula tenuiceps or R. sanguinaria under conifers/pines, but it is probably a group of species, and also not the same as the European one in the case of R. sanguinaria. We are trying to downvote these identifications for this reason. Hopefully, any people interested in identifying mushrooms will pitch in and help to vote any Russula that is being called Russula sanguinea in the eastern US back to genus level anyway, but we are concerned with a few other species too. Read fungee's journal post here [2]. Check out the master list here [3]. Another thing that is daunting for Russula ID, there are well over a hundred known red Russula in the east, many are not named yet, and, if they are, the name is not in use.

/r/mycology had to say stop posting “please identify this mushroom” because it was so common. I’d imagine its easier with insects. And you don’t have as many people who care because they aren’t trying to eat them as often.
I still like to ID random bugs I find in my house and backyard and it’s always a probability exercise.
Those tree identification apps by taking a photo never work. I used it at a UofT garden where every tree was labelled and it got it wrong every time. So even the ML is way off.
There are a lot of mushrooms that are very easy to identify, and learning edible mushrooms is imho a lot easier than learning edible plants. But if you pick up mushrooms at random then yeah, it's generally extremely difficult.
That whole experience made me very skeptical of citizen-science projects once I knew how much training was required to do good work. While they are a great compliment to professional research they are no replacement (though often funders are treating citizen science as just that).
