Challenge 1: Is Illustrator/Inkscape the Same Relationship as Photoshop/GIMP? — Solution Walkthrough

What's genuinely the same:

Both pairings share the exact same underlying framing this chapter
reapplies from Raster Editing Fundamentals: two applications built
around the same discipline (raster editing in one case, vector
drawing in the other), not two versions of the same platform. In both
pairings, one tool is a subscription-only industry standard and the
other is free and open-source, yet genuinely capable of professional
work.

What's genuinely different:

The specific technical differences aren't the same. Photoshop and
GIMP's real differences (per Raster Editing Fundamentals) center on
things like non-destructive adjustment layer maturity. Illustrator and
Inkscape's real differences, per this chapter, center on native file
format (proprietary .ai vs. open .svg) and ecosystem size (Adobe's
deep integration and commercial plugin market vs. Inkscape's smaller,
free extension ecosystem). The underlying discipline is different too
— raster pixel editing vs. vector path drawing — so the actual skills
being compared aren't the same skills at all.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise checks that the shared "two tools, one discipline"
framing is correctly recognized as the same pattern across both
pairings, while the specific technical differences named in each
course are understood as distinct, not interchangeable.
