Seeing the Bloomberg article was, for me, a reminder of the excellent info provided by this discussion forum. We learned of this BHE presentation over two months ago, courtesy of MMM20's post of lst 23-Nov, and then it was posted on the main BRK website -- appropriate, since it is material to understanding the company's business. Re BYD, I don't see any rationale for monetizing yet -- we are in early days of the fossil-->EV transition it seems. Re another monetization suggestion sometimes made, Apple, I used to be in favour of a partial monetization, reasoning solely from an overall share of the total market cap represented by AAPL and BRK. But now I'm not so sure. I had to consider an assist to a friend wiho has failing eyesight and loves to read serious and diverse material (old newspapers for instance, for historical research), and realized that Apple products would be the base I would trust for providing a trustworthy personal assistant for my friend. And I'm not an Apple fanboy, not even an Apple user at present. But I would not be willing to expose my friend to certain other software app offerings which are, in my opinion, too likely to abuse the trust one would have to place in a personal digital assistant. A bit of an eye-opener for me. So maybe Apple has further to run, as a business. Anyway, back to the point -- good stuff here at this discussion group, it is one of my most valued resources.
