1/ Charlie Munger: “We have the same problem as everyone else: It’s very hard to predict the future."

Seth Klarman: "An unresolvable contradiction exists: to perform present value analysis, you must predict the future, yet the future is not reliably predictable."
2/ Charlie Munger: “Stocks partly sell like bonds, based on expectations of future cash streams, and partly like Rembrandts, based on the fact that they’ve gone up in the past and are fashionable."
3/ "If stocks trade more like Rembrandts in the future, then stocks will rise, but they will have no anchors. In this case, it’s hard to predict how far, how high and how long it will last.”

Charlie Munger on the problems with a Keynesian Beauty Contest approach.
4/ “You have to figure out where you’ve got an edge and play within your own circle of competence. If you play games where other people have the aptitudes and you don’t, you’re going to lose. That’s as close to certain as any prediction that you can make." CM
5/ "We are in the business of making easy predictions. If a deal looks too hard, we simply shelve it. We’re a tortoise that has outrun a hare because it choses easy predictions. Some of our success we predicted and some was fortuitous. Like most human beings, we took a bow.” CM
6/ “People have always had this craving to have someone tell them the future. There’s always been a market for people who pretend to know the future. Listening to today’s forecasters is just as crazy as when the king hired the guy to look at the sheep guts." Charlie Munger
7/ "It’s highly likely the people who confidently think they know the consequences – none of whom predicted this – now they know what’s going to happen next? Witch doctors. You ask me what’s going to happen? Hell, I don’t know what’s going to happen." CM forbes.com/sites/phildemu…
8/ "Having a significant excess of real value per share working for you means that all kinds of good things can happen to you. You have a huge margin of safety by having this big excess value going for you."

9/ My friend Nick asked yesterday what Charlie Munger would be like on Twitter. We will never know, but Charlie has said: “To make teaching endurable, it has to have enough wiseassery in it." davisfunds.com/document/video…
10/ I was walking in yard today getting in my 10K daily step minimum and my neighbor yelled at me: "Nice Munger Twitter thread yesterday. You should write a book about him!"👀

What business is this?
You wanted to see my favorite chart in a S-1?
Have you adjusted to all this adjusting yet?

Is "adjusted EBITDA" redundant since it's adjusting what was already an adjustment?

Should the Department of Redundancy Department be contacted?

1/ "Starlink’s initial pricing — $100 per month and $499 to purchase the Starlink user terminal — is not a beta-only introductory price but reflects what pricing will be in the full commercial service, Starlink Vice President Jonathan Hofeller said."
"Right now there’s a huge amount of demand [for Starlink service] which is excellent. It currently exceeds current supply,” Hofeller said SpaceX hopes to lower the cost of the terminal over time." satellitetoday.com/business/2020/…
3/ A Beta user said: "the system represents a massive upgrade over his DSL provider. If you were to just use Starlink to watch YouTube or Netflix where they download a buffer, it'll feel like great city cable internet. Upload ranges between 10 to 38Mbps.” news.google.com/articles/CAIiE…

Charlie Munger: “There are all kinds of wonderful new inventions that give you nothing as owners except the opportunity to spend a lot more money in a business that’s still going to be lousy." "Nothing sticks to the ribs of owners."

Is there a barrier to entry for fake meat?

"Eight brokerages cut their price targets" *after* the stock went down.

"Beyond Meat said it co-created the patty in McPlant, but could not provide any further details, leaving analysts puzzled as to how much Beyond Meat could earn from the tie up." reuters.com/article/busine…

On Covid, please remember:

“A margin of safety is available for absorbing the effect of miscalculations or worse than average luck."

“A lesson inherent in any probabilistic exercise: the frequency of correctness doesn't matter; it's magnitude of correctness that matters.” MM
How should you act to reduce Covid transmission risks if you know or even suspect that there are no reliable models to rely on?

You have only one life.

“There is no way that one can sensibly assign probabilities to the unknown states of the world." 25iq.com/2018/09/08/ris…
“Avoid things like racing trains to the crossing... A lot of success in life and business comes from knowing what you want to avoid. What will automatically do the worst damage and how do I avoid it? Figure out what you don’t want and avoid it and you’ll get what you do want." CM

1/ 1994 was a pivotal year in technology. I had a ringside seat since Bill Gates and Craig McCaw were controlling shareholders in our startup. Part of that year I helped Bill write his book "The Road Ahead." Nathan Myhrvold was a co-author. Writing is an opportunity to think.
2/ One set up: In December 1992, John Malone announced TCI placed orders for 1M million digital set-tops. A story in the NYT predicted 500 channels of programming were on the horizon. In January 1993, Time Warner unveiled plans for a “full service network” to be built in Orlando.
3/ John Malone: ‘The arithmetic is pretty easy – if cable systems have got 50 analog channels, and you can do 10 to 1 compression, that wasn't a huge leap of mathematics to get you to 500 channels.” cablecenter.org/programs/the-h…

This BBC article isn't even wrong:

"China sends 'world's first 6G' test satellite into orbit"

1. 6G doesn't exist yet as a standard.

2. Running an experiment on a satellite using terahertz frequency is just that.

3. Gell-Mann Amnesia effect.

bbc.com/news/av/world-….
6G will not be just a radio frequency as is the case with 5G. People tend to want a single number to represent something so with a G they focus on achievable speed. In the real world, using less electricity and better utilizing low and mid band spectrum should be core to 6G
The focus of 5G and 6G should be on creating more value. Faster downloads using ever higher frequencies, especially if they are available almost never, are not the core problem to be solved in wireless (eg, operators using less electricity is new value). sdxcentral.com/articles/opini…
