Biowire and the Skillwire Expert System, Why Writers need to cross check. Options

p. 149 Emulation
Add the following sentence to the end of this section:
“Memorized Complex Forms emulating skillsofts are
limited to the rating of the original skillsofts and cannot be
improved either by  reading or Karma-expenditure.”

Well and since under emulating it goes like:

Emulation
Technomancers with the Biowire echo can use threading to
convert skillsofts (in storage accessible to the technomancer) into complex
forms that their neuromuscular system can process. To set up the
emulator, the technomancer makes a Threading (skillsoft rating) Test.
If the program contains other program ratings, raise the threshold by
the number of program options or rating points. If he succeeds, he has
converted the program into a complex form. He can now either sustain
the program as a normal threaded complex form of the same rating
or memorize the skillsoft as a complex form by paying an amount of
Karma equal to the rating (+1 for any program option or program
option rating).

And there is nowhere an other possibility mentioned, so it is quite obvious.
Pre errata: You could not make it up from scratch.
Post errata: You are also not able to improve it.

And do not give me, it is underpowered. You get a skill worth around 18 Karma for 4. I guess it is a good deal.
To make up any skill you want in one complex action is.... (Since you got at this point at least 6 resonanz and I guess 6 threading, the skilllevel is around 4.)
Not to mention the possibilities for abuse if you convert it into a permanent complex form.
"Yes, my technomancer got firearms 12, where is the problem?"

Indeed.
