I can currently only see them used as accelerators of some type right now. Could see them used potentially for GPUs, but generally I suspect some form of compute first. GenAI anyone? SkyNET? But that is only if they can be made portable for laptops or phones which is still a major issue still needing to be addressed.

I don’t expect them to replace traditional chips in my lifetime if ever.

So, around 1947. Took about 14 years to get to being able to put into chips. So another decade and a half?

Edit: and another 15 to 25 years after that for it to be in consumer households?
