It is my dream to do research on applications of spectral algebraic geometry in homotopy theory one day. Specifically, giving a more uniform treatment for the results proved via scary computations (of which there are plenty, from my impression). There was a post on MO on how to become sufficiently well-versed in DAG so that you can do research yourself, but it reflected the tastes of the answerer to some extent (who is a fine mathematician, but more focused on motives, it appears).
Can somebody give a similar outline, but having applications to (non-motivic) homotopy theory in mind? Since we are homotopists, the local objects for DAG we are using are connective (or $k$-periodic for some $k$, maybe?) $E_{\infty}$-ring spectra.
