Not a good sign for the fake e-CONomy when even the Jia Hinds are reporting the prized NFT of one of the Masters of the Metaverse went to zero*....

And China was prudent to ban bitcoin and mining... the only mining that creates wealth are those that have net positive EROEI such as coal, uranium etc....

At its most basic simple essence, the concept of bitcoin is just a peer-to-peer decentralized general ledger, where all transactions are syncronized in a database table and this database is replicated on all machines running a full node... think of it as everyone participating in bitcoin runs a napster client (back in the early music sharing days) but instead of exchanging songs you exchange the excel spreadsheet of transactions, and each time someone buys or sells a bitcoin or fraction thereof, it updates a new record on the spreadsheet and those delta changes are pushed out, updated and syncronized across all the databases ran on all the computers...

Thats all bitcoin really is, no more and no less.

The NFT is a concept that exists on top of this crypto layer... An NFT is basically a crypto-lized version of A Star Registry.... back when that was a fad and people spent money on buying a Star for their loved ones (naming a star, or more precisely associating their name with a particular star within the context of a database known as a star registry) you didnt really own the star (we havent even reached Mars yet) and you couldnt prevent anyone else from viewing or enjoying your star and on top of that even astronomers didnt recognize nor go by your star name, since the Star Registry was a joke and not used by the scientific community...

Same with NFT...when you shell out $$$$$ to buy an NFT you cannot prevent others from making copies of the jpeg image, in fact you dont even own the rights to the image and cannot copyright it. Anyone can download and enjoy the image themselves without paying a penny, and at the end of the day what really you end up with is etching your name to a hash function inside of the database of a cryptocoin aka no different than buying a Star on a fake star registry...

At some point people realized spending more money on buying an NFT image of a car that costs more than the price of the real car itself probably didnt make a whole lot of sense...

This is less to do with where VCs want to invest, but more to do with what types of startups are available for VCs to invest. This is an even deeper problem for the US.

I made a similar observation a couple of months ago in this thread ( #12,057 ) :

4G started in the US.
5G started in China.

See the correlation ?

Japan is a society that has gone utterly and completely into decline. Not just standard "developed country growing slower" type decline but as in "falling behind the rest of the G7" to the extent that if this goes on for another generation or two, Japan will stick out in the G7 as having the lowest per capita income by a substantial margin, despite once having had the highest. It is already competing with Italy for the lowest spot. It may eventually fall out of developed country status. This process started not in 1945 as you would think, but around 1990. And not with a bang, but with a whimper. There was no sudden crash or crisis that predetermined Japan's fate. Rather it has been a slow grind of the decades. For most of the 1990s Japan was still quite an admired society even though the process had already started.

That's what happens when you combine 1980s-1990s America intent on undermining Japan through industrial and technological subterfuge while enforcing harmful currency regimes like the Plaza Accord. It doesn't help Japan when their own government prints money non-stop for 30+ years at ultra low interest rates. The coup d'etat is when large parts of the Japanese business community started following Harvard MBA comparatively advantage theory from the turn of the century. These things combined have gradually whittled down Japan's once mighty scientific, technological economy. Now they are on a steep steep demographic decline but who can say they are sorry for them? People who know their history and how they have handled their historical baggage won't be crying any tears for them.

Not much immediately or potentially even in the medium term. This is a step more practical than just basic research, like finding new elements or the Higgs Boson, but not much.

The techniques used may uncover new methodologies to create new technologies or may have some directly applicable for very bleeding edge, high energy tech (like fusion). That last has become a - forgive the pun - massive hot spot and feels a lot like the rush for heavier than air flight. LLNL had their success with inertial fusion confirmed and there numerous startups with massive backing (even a major defense contractor or two) in the US. There are just as many outside. A magnet like this (but less powerful) was created by the team pursuing magnetohydrodynamic bottles for fusion in Massachusetts.

The fundamental research and speculative tech development was one of the few really positive features of the Cold War. The Soviet Union and United States each sought the edges of knowledge and found exciting and fundamental pieces of our universe. Since the end of the Cold War, even slightly before with Reagan, that began to slide away until the world does not is not nearly as fast paced.

That is part of the reason I am thrilled China is rising. While cooperation is fine, competition yields faster results. A bipolar world of two major rivals would reignite that same frenetic quest for knowledge. Though, I hope, without the brush fire and proxy wars plaguing the Cold War like a bad case of monkeypox. Sadly, I doubt it, but time will tell.

Back more directly on topic, since something like this in the US was done by a fusion startup, this demo is probably for pursuing the Promethean fire of fusion energy.

A team of scientists from Beijing University of Chemical Technology created shoes that are made from all organic degradable materials. This is the first mass production degradable shoe in the world. The first batch of 500 pairs of shoes are given as gifts to students and staff of the university [for trial I am assuming].

Specifically, the sole of these leisure shoes are made from an organic degradable polyster rubber, the only kind in the world. The upper, lining, string, etc. are also made from organic degradable materials such as hemp, bamboo and cornstalk.

Every year, in China alone a billion of pairs of shoes are sent to dump grounds as waste. While the many of the upper parts can degrade over time, most rubber soles are not degradable and have become a serious environmental issue.

The team spent 18 years to develop this organic degradable polyster rubber. In compost, this rubber degrades into water and carbon dioxide. Up to 70% of the mass can degrade within 130 days. The rubber is made from natural organic raw materials. It costs similar to the regular rubbers.

In addition to shoe soles, the scientists have also created products such as tires, chewing gums, oil-resistent gaskets, polylactic acid toughener, from this buffer. They have built production line that has passed trial runs of capacity at 1000 tonnes.

8月16日，由其团队开发的全生物基可降解鞋（以下简称可降解鞋），全球首批500双全部作为“礼物”，送给了北京化工大学学生、员工。

白色板鞋、绿色走线，鞋舌上绣了棵椰子树，清新简约。别看它在外观上与普通的小白鞋并无二致，但是鞋底却藏着“黑科技”——把鞋底填埋在堆肥的土里，大半年后它便消失得无影无踪。

“你去试试普通的鞋底，埋在土里大半年后，鞋底肯定还是鞋底。中国每年产生多达近10亿双废弃鞋，如此大面积的鞋底污染不可视而不见。”张立群解释可降解鞋子的功用。

该款可降解鞋的鞋底利用北京化工大学自主开发的生物基可降解聚酯橡胶材料，鞋面和鞋垫则采用大麻纤维、竹纤维材料、玉米杆乳胶材料等。
“它有两大特点——目前世界上唯一可降解的橡胶材料、取材自然。”张立群说。普通的鞋子，棉、麻、皮革等鞋面可以在自然环境中降解，但橡胶鞋底却无法实现。过去多采用热解、高分子两种方式处理废鞋，但需要像石油一样重新炼制，多产生二次污染。
按照国家标准GB/T19277.1-2011，通过国家塑料制品质量监督检验中心检测，可降解鞋底橡胶在130天内可实现70%以上完全变成水和二氧化碳，不会对环境产生污染。

北京化工大学王朝教授介绍，为了满足国家“双碳”战略要求，开发全生物基鞋也成为我国制鞋领域的重要发展方向。北京化工大学先进弹性体中心经过18年的潜心研究，首创了生物基可降解聚酯橡胶材料，突破了高分子量多元共聚酯橡胶连续化生产工艺难题，完成了连续化千吨中试试验，开发了包括可降解鞋、可降解轮胎、可降解口香糖、耐油密封圈、聚乳酸增韧剂等产品。

近3年，该中心解决了新型聚酯橡胶加工与服役性能提升问题，攻克了可降解鞋底与鞋面、鞋帮的粘接问题，最终制备得到了符合性能需求的全生物基可降解橡胶鞋底。该鞋底在堆肥条件下可快速降解，110天内降解率达到70%以上，但在日常使用时可以保持稳定。

同时，利用制备的生物基可降解鞋底，其鞋面选择大麻纤维或竹纤维材料，鞋垫选择玉米杆乳胶材料，鞋带和鞋胶均选择了生物基可降解材料，经过多次研发及试穿，完成了全生物基可降解鞋的制做，打通了大规模生产的工艺流程，并进行了小批量化生产。王朝表示，后面将会与鞋业公司合作，尽快实现大规模量产。

Some people just can’t see past some headlines, or the first layer of application to see the real value of something. You can’t fathom why so many legitamite companies, and even the Chinese government itself, are racing to develop NFTs, and there is almost no chance you would listen to the actual reasons without going back to some nonsense about people getting scammed for jpegs.

Your driving license, passport, ID card, gym membership, tickets, vouchers, credits, bills, memberships, certificates, licenses, and tokens will ALL be NFTs which can ineteract with smart contracts financially and digitally.

Even jpegs of monkeys could be minted as NFTs and sold to idiots, but it’s not a sustainable use case imo, because eventually the idiots catch on and governments start to ban things.
