If someone is researching AGI, there's a good chance that "whatever the hell they want" is for everyone to have access to AGI, that's the most obvious motivation for doing so. You are confusing intelligence with psychopathy. I suppose it comes from living in a society in which the media-political establishment worships obscenely rich psychopaths.
In any case, I don't know why you're so convinced that AGI would be smarter than human intelligence. I would expect the first one to be pretty basic, that's how technology normally goes.
There are two cryptographic properties here. Collision resistance means it's not possible to create two different files with the same hash. The collision resistance of MD5 is broken, which is why that attack worked. They were able to get Microsoft to sign something which contained their data, and produce some different data at the same time with the same hash. It was an attack against collision resistance because they created one file and had involvement with the creation of the other.
"Here's a file and a hash, make your own file different to mine with this hash" is a different attack against a different cryptographic property, which as far as I know is still not possible for MD5. If you just make a file by yourself, and then tell someone else its MD5, nobody will be able to make a different file with that hash and so convince this person they have the right file. The attacker needs to have some input into your file in order to attack MD5. If they do, MD5 is broken.
What makes a video card "decent"? Why do you even need one in order to play great games? If everyone was saying a game was great 20 years ago, does it mysteriously become crap just because 20 years have now passed?
What sort of computer you need depends on what games you want to play, it's not something you can make universal statements about. If you love photorealism, then sure, you want a meaty graphics card. If you think Civ 2 is still the best Civ, then you probably don't.
If you make games with "AI", then any game you make will be the sort of game which anyone with "AI" can make. You'll have a thousand equal competitors.
If you want to succeed, (unfair or anticompetitive trade practices or dumb luck aside,) you need to make games which are good in a way which it's difficult to do. That means you need something your competitors lack. Uncommon human talents, and otherwise in game concept, management structure etc, the kind of situation which allows them to make a game good in a way "AI" can never match.
This is quite a good situation for illustrating the rather counterproductive economic observation that a business sector as a whole investing in technology actually has a tendency to decrease profits. Here you have Netflix diving head-first into being an outstanding example.
There are problems of ambiguity with this kind of thing. I will tend to use Google to navigate to different mapping services, for example, by putting in the name of the mapping service, or something like 'online maps' if I want a list of them all. But if I want Google Maps, I will just put 'maps' in, lazily figuring that the Google part is implied. But someone else just putting 'maps' in may well be trying to do a general search for maps.
The root of the problem is the same capitalists owning a search engine as owning a mapping service. Just like other problems like the same capitalists owning an operating system and a word processor etc.
