I dunno if LLMs will get better, but ML in general is a task of compression, and there is definitely a whole bunch of human knowledge and history that neural nets can compress.
Its not unfeasable in the future to have a box at home that you can ask a fairly complicated question, like "how do I build a flying car", and it will have the ability to
- tell you step by step instructions of what you need to order
- write and run code to simulate certain things
- analyze you work from video streams and provide feedback
- possibly even have a robotic arm with attachments that can do some work.
