I'm quite new to Sindome so my input may be flawed by lack of knowledge in what we can do IC but here is my take.
While the mix is dirt poor, there is still a lot of electronics. After all the criminal scum don't necesseraly need the flash to get theirs hands to get theirs hands on expensive stuff. And for the legit goods, the corps don't exactly sell the best stuff to poor people. Therefore there is a need for techies to deal with stolen eletronics or low quality ones.
I'm in favor of more use of tech skills that can allow for more interactions between Techies and other mixers.
While a scanin/scanout job related to say : Electro tech or programming might give a brainy charcater an IC job, it would not really give a way for them to roleplay their character with others apart from the "I work in the Repair shop".
But if you add a real use to the tech skill like :
-Electronics hardware breaking with use or time, as the corps would only sell low quality stuff to Red.
-SIC relay antenna that can be tampered with and repaired.
-One time use electical key to break into a specific kind of door.
-Progia and other connected appliances could be autolocked once reported stolen. This would need someone to crack them.
Then all the brainy character would have more opportunity to roleplay their archetypes with other players in a themely manner . For exemple :
SIC JoeBaka : "Damn, the quickterm I just bought won't do anything but blink red."
SIC RandomMano : "That term must have been dipped, you got conned chummer !"
SIC JohnTech << "Come to the Jun repair workshop in Red Central, I'll repair it if you have the flash SICer."
SIC Anon 1354 : "I need a Tech !"
SIC Anontech5646 << : What do you need chummer?"
Sic Anon 1354 : " It'd be a shame if the SIC stopped workin' in Sarz turf tonight at 3am" [sent to : SIC Anontech5646]
SIC Anontech5646 << : "If a mano were to part way with 50 kay that would happen."
Sic Anon 1354 : "I got the flash" [sent to : SIC Anontech5646]
SIC Anontech5646 << ""Meet me in the market, I'll be wearing a green poncho"
As seen in the exemples, the tech oriented characters fit in with the rest of the mix. They use theirs skills for shady purposes, not for the improvment of mankind or other bullshit the corps progaganda will tell you.
