Cameron is much more into ‘I love the deep sea’, has more senoirity as a legitimate deep dive submersible expert, but Gabe is giving him a run for his money.
That yacht Gabe has?
He bought the shipyard so he could direct them to refit the yacht to also have a docking bay and facilities for a submersible, (and also a LAN party room lol) which he has since gone on to use to plumb the deep seas south of Japan, mapping various trench beds in high detail, and possibly capturing some never before seen hadal zone creatures on camera.

He is literally playing Subnautica IRL.
Gabe also funds actual legitimate neuroscience / medical brain implant research. Unlike Elon’s Neuralink… which poached a PHD’s research team and then basically stole and claimed credit for inventing a certain kind of brain implant tech… and then ran around saying he was gonna change the world with this half baked over hyped tech, untill he got bored / came down from ketamine…
Gabe is a bit more hands off and just actually lets the experts do expert things, try to discover and invent new ways to help people with Parkinsons and such… the goal isn’t primarily to make money, it is to do research.

He’s closer to an old school American business tycoon… an actual philanthropist who has more money than he knows what to do with, so he throws it at things he thinks are neat and could contribute to society in some way.
Even Bill Gates, for all the shit he absolutely deserves to be criticized (if not imprisoned) for, he did and does throw a pretty substantial amount of money at cancer research, that has led to very useful research there.
Now, I still don’t think billionaires should exist, but, they do. And at least some of them do less horribly bad things with some of their money than say, I dunno, directly fund and bankroll fascist politicians.

































Actually, technically, the way teleportation works in Half Life/Portal universe…
They are aliens, extraterrestrials, they’re not from … a mirror realm, a distinct and different universe or timeline.
Xen acts as a kind of … bus stop, for the universe, if that makes any sense. But it does exist somewhere in our Universe, it is not in an alternate/parrelel universe/timeline ala Marvel different universes.
Xen is a relay, that, for whatever reason, seems to be a spot in the actual universe where transdimensional travel often … ends up at, or traverses through. Like a strange attractor in a chaotic system.
So this goes for the Combine as well. Xen, Vorts, Headcrabs, the Combine… they are all from our Universe, though they could be from totally different galaxies than our own.
The teleportation tech/system in the HL/Portal Universe works more like the Webway from 40k, than it is like the Warp from 40k.
It is a system / series of gateways in … string theoretic 11 dimensional space, that in our 3d experience of reality, appear as basically a complex network of subway tunnels, semi-stable wormholes. The Combine make great use of this, the Human Resitance barely understand it, but use it in different ways, and the Portal tech just most directly punches wormholes through 3d space via … fucking moondust and intensely technogically perfected spite, or something.
… even in the instances in the series where time itself is … paused or traversed… by G Man or the Vorts … these occurences seem to all take place inside of a single consistent and coherent universe.
