A dyson swarm is just a bunch of satellites, each harnessing energy from a the same star around which they are more or less are situated (what they do with that energy is up to them). They harvest a proportion of the star's energy anywhere on the range between 0 (non-inclusive) and 100% (inclusive). Your description is one possible end state of a Dyson swarm, and itself includes a subjective measure (what you consider dramatic might not be what I consider dramatic).

Your description of it as a megastructure might explain some of the confusion: it wouldn't be a structure, but rather a formation of satellites not physically connected to each other.

How do you build a swarm of satellites? Well, first you make 1 satellite, then you make another... :)

My description is Freeman Dyson's description. Naturally you are allowed to come up with ImPostingOnHN's Swarm, which includes a case of zero satellites and no effect on the star emission whatsoever.

Sure and the end state of completing Dyson Swarm in Solar system is not achievable with the technology we have. Now let's move on to discuss if one man with a rifle but no vehicle constitutes a Motor Rifles brigade.

Sure, for one possible end state.

The point is that we have the technology to start, because we've already started. Thus, it is achievable given enough time and effort with our current level of technological advancement.
