Answer 1

We lack the amount of materials to make a Dyson sphere. We lack the engineering knowledge and know-how to make a Dyson sphere. We lack the ability to travel to the right orbit to make a Dyson sphere.

Honestly, we’re about six tech levels out from a Dyson sphere. What this means is we lack the tools to make the tools needed to make the tools needed to make the tools to make the tools to build a Dyson sphere.

We understand the concept of a Dyson sphere, but we’re at least a thousand years away from being able to attempt one.
