I can suggest an equation that has the potential to impact the future:
H|ψ> = E|ψ> + AI
Here, I have chosen the time-independent Schrödinger equation, to symbolize the fact that AI is the most important innovation of all time.
...
This is all bullshit of course. Everyone knows that the AI term should be included in the Hamiltonian anyway 🙄
Yes, there was a perfectly fine, upgradable memory standard before. And many 486s were also perfectly fine, upgradable computers.
The fact that a new technology makes it so we can have our cake and eat it too
upgradability without any compromise
is a fantastic innovation.
