It sounds like you have at least an undergraduate CS degree. Go ahead and recreate Twitter and share your GitHub repo for us to review. No need to rush. I'm happy to wait several decades for you to complete the project.
I mean how hard could really be since nobody really has access to the fire hose and only gets showing a little bit at a time which is really horizontally scalable. I mean let’s do the math when NVME Drive can write at 4gbps so scale that to match the influx of data rate with room to spare. The point is Tesla engineers are going to look for nefarious action, not to worry about corner cases. what a non sequitur argument that is
And the code is not the hard part it’s the scaling in the architecture to handle the rate at which the data will flow.
