As a side note, I think LLM frenzy would be dead in few years, 10 years time frame at max.

The majority of the world's computing systems runs on closed source software. Believing the opposite is bubble-thinking. Its not just Windows/MacOS. Most Android distros are not actually open source. Power control systems. Traffic control systems. Networking hardware. Even the underlying operating systems which power the VMs you run on AWS that are technically open source. The billions of little computers that form together to make the modern world work; they're mostly closed source.
