It will teach her how to input text and select objects and stuff! Cam goes back to looking at the resurrection ritual to make sure he will not be surprised by any steps.

That's going to take a lot of research. The book of ignorance was written by a poet and none of these people had ever heard of scientific rigor. 

Well, it's important to be confident of these things. After a bit he looks up and asks Wilbur, "Do you want a computer too?"

"Yes please." 

Computer! "This one's pretty much like hers, let me know if you want anything that isn't on there."

"Thank you," he says, metaphorically swan-diving into future science texts. 

Wag wag.

Resurrection ritual!

There are some components that would be difficult to source both ethically and conveniently if he were not a demon. 

Fortunately he is one! Any other pitfalls?

Occasionally the reanimated crave human flesh. This is less likely the better you perform the ritual but no one has worked out how to eliminate it entirely. 

Welp. What are the axes of ritual quality that affect that, and how much do they crave it.

If you do the ritual perfectly then even if the resulting resurrected person craves human flesh they can do without and are likely to be perturbed by it. 

Since they've never heard of scientific rigor the notes on axes of quality are sorta sparse but the gist of it is that if you fuck up, instead of failing gracefully by doing nothing it will probably fail ungracefully by creating a revenant that will try to eat you. 

Well. Cam will put a bunch of hours into getting all the sources he can on this and organizing them more sensibly until he thinks he can get it pretty darn perfect.

Cam has many advantages in this area, such as previously unparalleled research resources and the ability to notice that refusing to pronounce phonemes not found in his native tongue is "stupid" and not "fine because ethnocentricism" 

Cam is very fortunate. But if this research project looks like it will take more than a couple days he's going to take a break to go for a malaria-eradicating shuttle ride.

Depends on how exquisitely careful he wants to be about not having to feed Ben Franklin basement-dwellers. The low-hanging fruit can all be gathered within the first couple of days but the point of diminishing returns is not a point of no returns.

"Hey guys," Cam says after he's been at it for nine cups of coffee, "this is gonna take long enough that I don't want to wait to eradicate malaria until it's finished. Will you be okay without me for a few hours while I go place lots of mosquitoes?"

"I'm good," Lucy says, absorbed in her algebra curriculum. 

"We'll be fine," Wilbur agrees, taking notes on his computer as he pores over the Necronomicon. 

"Cool. Here are some snacks in case either of you get hungry." He makes an insanely large bag of trail mix.

"Thanks!" A "hand"ful of granola flies out of the bag and disappears. 

"If you need me back early, write 'letter to Cam' on a note and I'll get it next time I check my mail." Cam makes a smaller less obtrusive shuttle and heads Earthward.

While cruising over Africa releasing infertile mosquitos, he may observe an inhabited area with a temple in an odd architectural style, with spiral pillars and a giant statue in front of a not-quite-human woman. 

...he will fly a bit lower over this area.

The people living nearby seem not quite human in roughly the same way, somewhere between a gorilla and a neanderthal in build, and covered in white fur.
