IIRC Transmeta's technology came out of HP (?) research into dynamic inlining of compiled code, giving performance comparable to profile-guided optimization without the upfront work. It worked similarly to an inlining JIT compiler, except it was working with already compiled code. Very interesting approach and one I think could be generally useful. Imagine if, say, your machine's bootup process was optimized for the hardware you actually have. I'm going off decades old memories here, so the details might be incorrect.
Similar technology was developed later by Nvidia, which had licensed Transmeta's IP, for the Denver CPU cores used in the HTC Nexus 9 and the Carmel CPU cores in the Magic Leap One. Denver was originally intended to target both ARM and x86 but they had to abandon the x86 support due to patent issues.
I'm not sure that that's really correct; they were very desktop-oriented.
It was wrong, but it was controversial among experts at the time.
I’m glad that they tried it even though it turned out to be wrong. Many of the lessons learned are documented in systems conferences and incorporated into modern designs, ie GPUs.
To me transmeta is a great example of a venture investment. If it would have beaten Intel at SPEC by a margin, it would have dominated the market. Sometimes the only way to get to the bottom of a complex system is to build it.
The same could be said of scaling laws and LLMs. It was theory before Dario, Ilya, OpenAI, et al trained it.
However, if you add it onto a better CPU it’s a fine technique to bet on - case in point Apple’s move away from Intel onto homegrown CPUs.

A similar product launch was the Segway, where we went from this incredible vision of everyone on Segways to nobody wanting one.
The hype was part of the problem with Transmeta. Even in it's delivered form it could have found a niche. For example, the network computer was in vogue at the time, thanks to Oracle. A different type of device, like a Chromebook might have worked.
With Torvalds connected to Transmeta and the stealthy development, we never did get to hear about who was really behind Transmeta and why.

Other than that, it seems to have sunk without a trace.
