The current AI tools are Large Language Models (LLMs), pretty much just advanced chatbots. These are neural networks which process and generate texts. This ability is not really helpful for an "Artificial Engineer". This has to be a different kind of neural network, one that processes formulas, design ideas and numbers. Also a simulation module certainly helps.
The current AIs can do more than just processing words, because the text generator is used as an interface to other software- and ai modules. E.g. ChatGPT seems to have a chess module since a few months. Before that it looked like what a text processor can do: copy moves from other games which look similar, meaning it creates pieces out of thin air and does illegal moves pretty often.
