Correct!
It's a battle of efficiency, where the cost of wires + skillsoft vs buying a skill with Karma should be a cost-benefit analysis that, ultimately, revolves around one question: How valuable is your Essence? The original mix has Activesofts a touch cheaper, so that you'd at least break even at all levels, rather than as it stands now, where you pay a touch more for Rating 1 Activesofts than you do fo just buying a skill. The current chart looks, roughly, like so:
(Rating/Karma/Karma in Nuyen)

1/1/0.5
2/2/1
3/6/1.5

Using these charts, you can start finding the break point ... at break point, the cost of buying things with Karma, or via SKillsofts, is the same(ish), while every 'soft you buy after that is effectively profit, IE getting a skill at a cost lower than the Karma cost. The initial investment in a Skilljack/Skilllwires servs as a 'buffer' to make the entry expensive, but do-able, but those that lean heavily on the tech will see an eventual upside.
On a Skilljack 1, you never see a Break Point on Knowsofts, but break even at 20 Language (1) 'softs.
Skilljack 2, 10 Knowledges or 5 Languages
Skilljack 3, 5 Knowledges or 3 Languages
Skilljack 4, 3 Kowledges or 2 Languages
Skilljack 5, 2 Knowledges or 2 Languages
Skillhjack 6, 2 Knowledges or 2 Languages
On Skillwires (Which also require a Skilljack whose cost is NOT reflected here!)
Skillwires 1 never gets a Break Point
Skillwires 2 has a break point of 20 Active Skills
SKillwires 3, 6 Active Skills
Skillwires 4, 4 Active Skills
Skillwires 5, 3 Active Skills
Skillwires 6, 2 Active Skills
Still not *quite* where I wanted, but almost.
Hardwires, both Knowledge and Active, are almost always 'profitable'... I think the Break Point's at 2, but I don't have that chart handy I'm afraid.
