We've only had the tech to be able to research this in some technical depth for a few decades (both scale of computation and genetics / imaging techniques).
This would not fund the people you want it to fund.
Bad or borderline actors would be so much better at creating whatever metrics you're basing things off of that the actual value creators wouldn't stand a chance.
As for me that's a risk I'm willing to accept in return for the freedom of the code.
I'm not going to deliberately write code that's LIKELY to do more harm than good, but crippling the potential positive impact just because of some largely hypothetical risk? That feels almost selfish, what would I really be trying to avoid, personally running into a feel-bad outcome?
You can easily print bricks that work. They will just require more force to assemble than normal because you have to make them slightly undersized to make up for the lower tolerance.
Just think of how many 3d prints you've seen that consist of multiple parts friction for together.
Why wouldn't you want it to be a computer? Then it can be connected to your devices AND also do the job itself in a situation where it's awkward to connect to a device.
If already needs a computer in it to drive menus / modern display protocols. Having that computer be powerful enough to also decode content is barely an extra cost.
Why are people assuming they did store it after the process was completed?
With the relatively low number leaked here it could have been information collected actively during an ongoing breach, not a dump of some permanent database.
They're not meant for normal consumers who just want to use the model for work.
