【推荐3】In the early days of covid-19, the tech industry was consumed by a sense of excitement. With billions of people locked down at home, work and play were shifting online. Many hoped that the new normal would spark a huge productivity boom as firms digitized and workers spent less time commuting. The excitement was most evident in stock-markets, where any firm related to this trend saw its share price surge. The tech-heavy NASDAQ rose by 88%.

The crazy has ended. Today the lockdown lunacy index(疯狂指数) — which includes Netflix, a streaming service; Peloton, a maker of fancy exercise bikes; Robin-hood, a stock-trading app; Shopify, and e-commerce platform; and Zoom, a videoconferencing firm - has fallen by more than 80% from its peak.

How worrying is this return to Earth? To be sure, some of it reflects gloomier prospects for the global economy. And it is disappointing that two years of digitization and remote work have not provided clear evidence of a productivity boom. Yet there are reasons still to be techno-optimistic. Much of the early enthusiasm may simply have been focused on the wrong types of firm. Though the pandemic darlings have fizzled, the shift towards ever greater digitization continues. The true winners are not the flashy consumer-tech firms, but the companies that provide the infrastructure to enable this shift.

Look beyond the boom and bust of consumer tech, and you see the real successes. The market for the infrastructure technology that underpins people’s daily lives, such as cloud computing, cyber-security and digital payments, is booming. The cloud-computing industry is expected to grow to almost $500bn this year, up from $243bn in 2019. Amazon’s cloud offering, the largest in the world, is still growing at 33% each year. It accounted for three-quarters of the firm’s operating income over the past 12 months, and is propping up the tech giant’s ailing e-commerce business. Its closest rivals are the cloud services of Microsoft and Google. Their annual sales are growing by 40% and 36%, respectively.

Cloudification has created new demands for cybersecurity, another tech winner. The combined revenue at the three largest listed cybersecurity firms has almost doubled since the start of the pandemic. Their market capitalisation has tripled, and has come down only a fraction since the start of the year. Digital payments are another bright spot, thanks to lockdowns and social distancing. Three-quarters of iPhone owners use Apply Pay, up from half in 2019, and nine out of ten American retailers now accept it as a payment method. Almost 200m people in India and China have used some form of digital payment for the first time since the onset of covid.

The bubble may have burst on the pandemic’s darlings, but the drumbeat of digitization continues. The less obvious technologies that provide the underlying infrastructure for the shift are the true beneficiaries of covid. Whether these will fuel a productivity boost one day remains to be seen. But there was more going on during the pandemic than lockdown crazy.

-Salvador Dali

“Every morning when I awake,” wrote the artist of the soft watches and burning giraffes, “the greatest of joys is mine: that of being Salvador Dalí. . .” The Spanish artist, so famous and so rich, was creative not only in his art. He talked nonstop too; his favorite topic was how to be a genius. “Oh Salvador,” he concluded, “now you know the truth: that if you act the genius, you will be one!”

Had he lived during the Renaissance (文艺复兴), Dalí would have been recognized sooner as a genius. In our age, though, which he felt was growing increasingly stupid, Dalí represented an air of challenging and annoying everyone else. Today he is ranked alongside Picasso as one of the modernist greats, and the general public quite clearly loves his art as well; therefore, it is difficult to understand why he should still be seen as so challenging and annoying, and why many people should still consider him as mad. Dalí himself declared: “The only difference between myself and a madman is the fact that I am not mad!” Writer Michel Déon once said, “His personality -whether it is loved or hated-is based on something deep and appealing, and that is his roots and his feelings. Roots that reach deep into the earth, absorbing everything that has been produced in four thousand years of painting, architecture and sculpture. Feelings that are picking up things to come, from the future, expecting it and flying to it at lightning speed. It cannot be emphasized enough that Dalí is a man of tireless scientific curiosity.” One might say that Dalí was typical of his age: he had grasped how to make himself a star.

But there was more to Lamarr than met the eye. An enthusiastic inventor, she worked on everything from a tablet to frequency hopping — a World War II-era secure communications technology that’s used today in wireless internet, GPS, and cellphones, which makes her regarded as the “mother of Wi-Fi.”

The Austrian-born Lamarr grew up in Vienna without a lot of education in science. Her natural curiosity drove her to explore and understand the world around her.Therefore, her father, who was also interested in science and technology, often walked with her around the city, pointing out what made things work.

Lamarr's informal scientific training continued when, as a young girl in 1933, she married a wealthy arms merchant who worked with the German and Italian military. When all of these generals and admirals were coming around, she listened, absorbed and learned.

The marriage didn’t last, and Lamarr set out to seek her acting career. When she got to Hollywood in the 1930s, she quickly became an international icon(偶像). After watching World War II break out, with growing concern, Lamarr began inventing on her own. As an Austrian, she thought she should do more to contribute to the allies’s(同盟国) war efforts.

In Hollywood, Lamarr met George Antheil, a composer who would become her cooperator on the frequency-hopping technology. Together, they invented a system that made it harder for the enemy to track or jam signals on radio-guided weapons. However, it wasn’t until 1997, three years before her death, that Lamarr received professional acknowledgment(认可) for her invention.

Lamarr played the role she expected to play in Hollywood-a beautiful object to admire on the big screen. However, She never yielded to society’s expectation to women. Her story really encouraged young people, and especially young women, to go into fields that are traditionally male-oriented, and not to judge a book by its covers.
