Bots Grade Your Kids’ Schoolwork—and They’re Often Wrong – WSJ – not surprising that Bots get grading wrong. A lot of ‘AI’ is math, it isn’t that far along from Business Intelligence systems of the 1990s. What would have been called fuzzy logic in the 1990s is now ‘AI’ bots; both of which rely on mathematics from the 1960s. ‘AI’ bots using Bayesian statistics rely on mathematics from the 18th century. ‘AI’ bots require a large amount of training. Bots don’t develop a ‘universal’ intelligence.

Battery life: the race to find a storage solution for a green energy future | Financial TimesMIT’s Prof Sadoway believes that technologies need to be based on more abundant materials than those used in lithium-ion and vanadium batteries such as aluminium, sulphur, calcium and antimony. In 2005 he helped develop a liquid metal battery that uses calcium and antimony and a molten salt electrolyte. The company that developed it, Ambri, was backed from the beginning by Mr Gates, who invested in it after watching Mr Sadoway’s chemistry lectures online

‘Humaning’ and the greatest marketing bullshit of all time – Marketing WeekMaslow built his model from qualitative research on the Native American inhabitants of the Blackfoot reservation who later pointed out that his whole theory was entirely incorrect when applied to their culture and identity. The hierarchy has subsequently been criticised on the basis of missing stages, putting stages in the wrong sequence and the fact stages change according to circumstance, culture and geography. So basically everything. But the dreaded hierarchy proved a hit with marketers who had no formal training but wanted something scientific-looking and faintly European-sounding to beef up their empty marketing plans. Its prevalence across every crap marketing plan (along with the equally redundant SWOT analysis) serves only one positive: to identify badly trained marketers and crappy marketers at 50 paces.

Scaling back – Why commercial ties between Taiwan and China are beginning to fray | Business | The Economist“Little Taipei”, as Kunshan is known, illustrates a broader phenomenon. Exact estimates vary, but as many as 1.2m Taiwanese, or 5% of Taiwan’s population, are reckoned to live in China—many of them business folk. Taiwan Inc has not let fraught political relations with China, which views the island as part of its territory, get in the way of business. Taiwanese companies have invested $190bn in Chinese operations over the past three decades. Foxconn, a giant Taiwanese contract manufacturer of electronics for Apple and other gadget-makers, employs 1m workers in China, more than any other private enterprise in the country

Grocery Drives Walmart Online Orders – Consumer Intelligence Research Partners, LLCAmong all US Walmart.com customers, CIRP estimates Walmart+ has 2.6 million-3.4 million members as of October 31, 2020, with 12%-15% of Walmart.com customers joining. US Walmart.com customers that shop for groceries at Walmart.com are two times more likely to report a Walmart+ membership. “Walmart launched the Walmart+ membership service in the quarter, and we estimate a range of membership that suggests about 3 million Walmart.com customers joined,” said Mike Levin, Partner and Co-Founder of CIRP. “At that level, it seems like a success, especially after only six weeks. Of course, grocery customers found it particularly attractive. Like Amazon Prime, Walmart+ is most valuable to regular Walmart.com shoppers, so it appealed to those grocery shoppers right away. And like Amazon’s experience with Prime, Walmart appears to want to build on that natural affinity to gain greater share of online shopping for those customers, and then to entice less frequent shoppers to grow their online shopping habits.” – groceries are over 30% of sales (food, household and pets 25%, clothing shoes & accessories 16%, same for pharma and electronics and office supplies were about 12%) (PDF)

Muddy Waters accuses YY and Bigo of faking their revenuesSingapore-based analyst Ke Yan of DZT Research, told Bloomberg that the strategies discussed in the Muddy Waters report are aimed at boosting YY’s popularity among users instead of inflating revenue. Chen Da, executive director of Anlan Capital, offered Bloomberg a similar view. “You can’t really apply the research methods used to collect fraudulent evidence against real-economy or manufacturing firms to internet firms.” He added that their “business model does pay off and there is real cash flow brought in after the fakes ‘get the ball rolling’.” – sketchy growth hacking rather than fraud

6 Points to Consider Before Betting the Farm on ‘All Made in China’ | EE TimesSome “three-nos” companies with “no experience, no technology, and no talents” have joined the IC industry. Some companies have insufficient knowledge of the law of IC development and blindly start projects. The risks of horizontal duplication of construction are apparent, and even the construction of individual projects is stagnant, and the factory buildings are empty, causing waste of resources. In this regard, Wei said that we must respect the law of industrial development and overcome the rapid development shooting for quick success. Since 2007, China’s wafer manufacturing capacity has increased rapidly in the world, far higher than other countries and regions. In 2019, China has 199 integrated circuit wafer manufacturing production lines (above 4 inches), of which there are 28 12-inch production lines and 35 8-inch production lines (including 1 pilot line). The enthusiasm for investment and construction of factories in various places is high, but a number of manufacturing projects are facing unfinished shutdowns. The blind impulse that violates the development law of the semiconductor industry is worthy of vigilance
