I think it cuts both ways because these types of people are the ones who can wield this technology as a Swiss army knife to do really interesting things and in fact if they can build on top of their own peers' collective toil then they can avoid doing that toil themselves and potentially do greater things.. at least that's the theory.

If some of them want to temporarily participate in the toil, nothing wrong with that, after all that's what doing a PhD is anyway. Same goes with homework and problem sets earlier in the science trajectory.

The greater fear that we won't need these types of experts b/c in the future machines will have all the intelligence or the ratio of humans with expertise to the overall population will somehow drift is certainly a societal level concern as we offload intelligence to the machines but the flip side of it is that will not be able to learn how to higher level of abstraction or more quickly than ever before enabling more of us to actually develop expertise, or at least a new type of expertise.

Not that Star Trek is meant to be real but when I think about the crew of the Starship Enterprise I imagine few of them actually know all of the ins and outs of how the warp drive work but they're able to travel around with star system

Star Trek's warp-capable space ship is a fictional analogy for nuclear submarines and aircraft carriers, which are designed by geniuses to be used and maintained at sea by people who are not geniuses and who do not understand all the ins and outs of how atomic energy works.

There are hundreds, maybe even thousands, of people today using computers without understanding how transistors work or which register they're writing to at any given moment. Many of these people also drive cars without understanding how gears can shift or how the radial motion of the main drive shaft gets transferred in the transverse direction to the drive axle. I suppose a few of them wear clothes without having ever sheared a sheep and without knowledge of the best way to felt wool.
