Guardian's skills may come in more handy than his drugs in this case, Dragon. You could do research into things like, how to treat a severe seizure victim, how to stop an embolism, how to slow excessive heart rate... stuff. If you have any questions, you may always shoot me an email, PM, or Discord message.
What will happen to those who don't go along for the adventure? I don't know... but lone edgerunners are great targets. 
Here's the thing, Mathis is a techie. He builds things, fixes things, and disassembles things. That being said, when infiltrating a compound of unknowns run by netrunners, there are more than likely going to be nasties of all kinds. Think of the techie as kind of a thief character class. Lockpicking, disassembling traps, etc. Every class is useful in every run depending on how creative you are is how useful they are. Also, remember that you don't earn experience points in CyberPunk. You earn character points or, as I like to refer to them, Improvement Points, that are directly associated with the skills you use. Don't use a skill, don't ever expect to advance in it without chipping.
Okay... I've got three posts from two people. We're bordering on three weeks between my posts. Any way we can get back to once per week?
