Agreed, I still do hope they can maintain some of their promises. However until now, I have not really seen any real advances towards making something useful.

I do not have a deep knowledge of quantum computers, but I know plenty people working on them and often get to talk about it.

I know people working on chemical problems who are basically approximating atoms to point charges. And either way those calculations are slower than on a CPU. For the uninformed, in chemistry the interactions between electronic orbitals is fundamental; this is in no way an approximation useful to obtain any kind of information.

This is fine, I understand methodologies take time to develop; however as far as I understand it those techniques they're using are mathematically limited to using point charges: no matter how much they improve them that'll be the highest level of accuracy.

I hope someone finds a way to handle such things better: as much as you can make a great machine learning model you're always depending on available data.
