From the point of view of form, the type of all the arts is the art of the musician - Oscar Wilde

• Hub, like great music and stories, taps into universal themes, resonating with our deepest desires (return home) and anxieties (far from home)

• Spoke is that of Odysseus: a departure to troy, a host of struggles on his way back, and his eventual return

• Network is captured in this Review. Taken from the musician perspective, our ii-V-i cadence is beset by insertions, obstacles, challenges. Missingness of one or all of the principle components of data, code, server, models, weights, and profiles is what is at stake (but perhaps migration represents redefining home?):

  • \(f(t)\)

  • \(S(t)\)

  • \(h(t)\)

  • \((X'X)^T \cdot X'Y\)

  • \(\beta\)

  • \(SV'\)
