The reason they are blackboxes is because they are function approximators with billions of parameters. Theory has not caught up with practical results. This is why you tune hyperparameters (learning rate, number of layers, number of neurons ina layer, etc.) and have multiple iterations of training to get an approximation of the distribution of the inputs. Training is also sensitive to the order of inputs to the network. A network trained on the same training set but in a different order might converge to an entirely different function. This is why you train on the same inputs in random order over multiple episodes to hopefully average out such variations. They are blackboxes simply because you can’t yet prove theoretically the function it has approximated or converged to given the input.

All hail the hypnotoad! @_@

I really ought to start looking at usernames before I read comments.

Uh oh!

Even if there is nothing wrong with Meta trying to federate with the Fediverse, I do not want them here.

Honestly, at this point I am quite jaded and sick of the shenanigans of big tech. Repeatedly they have violated the trust of their users. Unless they show active change in the way they conduct their operations for the benefit of the end user and not advertising agencies, I would prefer to not have them in my life if I can help it.

EDIT:

I might have misread the intention of your post. If you are asking about the fallout of Meta federating, there is a possibility that they attract too many users to their platform. This is my personal anecdote. I wanted to get rid of all products owned by Facebook to the point where I told my contacts that I am switching to Signal and will be uninstalling Whatsapp. I even reasoned with them that I wanted to choose not to use Whatsapp, and that I still wanted to communicate with them, albeit on Signal. I even emphasised that I wasn’t asking them to uninstall Whatsapp. Ultimately, only about a third of my contacts joined Signal.

Everyone says there is a choice in not using Whatsapp, but is it really a choice when there is no one to talk to on Signal? That is my worry that something similar would happen with Threads.

I did the same too. I liked my current instance’s affinity to technology and figured I may as well join a smaller server to avoid the strain of the Reddit exodus.
