A current that I think doesn't yet have the deck to go with it.

In general I believe Predictive Algorithm will be a current that works exceptionally well for Harpsichord Studios, the upcoming NBN ID that only allows one agenda to be stolen per turn, in a deck filled with the ever expanding suite of NBN agendas that NBN doesn't mind being accessed.

In this deck it'd have the advantage of being cheaper than man hunt as a way to turn off potentially nasty runner currents (such as Hacktivist meeting), make any rush style play put more pressure on the runner (as they'll need to find 2 extra credits in addition to drawing for breakers) and can provide big swings when things like TGTBT's and explodapalooza are accessed but the runner can't afford to steal them.

While turning the next agenda stolen into a mini NAPD might not be the most valuable effect in a faction full of currents with more teeth; Predictive Algorithm might find a place in niche decks and as a cheap current for decks that just want an easy off switch for Runner currents.

There are decks in my meta that focus on high taxes and difficult-to-steal agendas; one PE comes to mind that runs with Fetal AI, Future Perfect, Utopia Shard, and NAPD. Adding two more credits on top of these already pricy agendas would, I think, be brutal - especially as it targets runner currents. I don't, however, think NBN really has the oomph in-faction the way Jenteki does to maximize the card. —
I think the issue with the out of faction idea is that I'm not convinced the effect is strong enough to make it worth springing the influence for. Though considering PE doesn't (at least off the top of my head) really have a current it runs naturally PA might work in a current heavy meta. —
