Amazon expands during the pandemic when retail on line delivery has helped people reduce trips to the grocery or retail stores. Amazon hired 427,000 people to expand its workforce to 1.2 million people by November 2020, 9 months into the pandemic. Almost doubling the employee workforce. These workers are mostly at warehouses, with some software engineers and hardware specialists. This includes hiring in India and Italy and is worldwide hiring. This does not include 100,000 temporary workers for the holidays, and 500,000 delivery drivers working for contractors.  Only hiring of 230,000 people by Walmart about 2 decades a ago in one year comes close. Walmart hired 180,000 people during the pandemic. Walmart has 2.2 million employees. With the expansion underway Amazon looks to become the largest private employer in the world in 2 years, say experts.  Amazon pay is $15 an hour after an increase of $2 recently. Its coronavirus safety practices have been upgraded after early criticism in April and May. Recent expansion in Italy and in India are also part of worldwide expansion after Walmart has pulled back from its worldwide expansion. This also shows how quickly major aspects of life are changing during the pandemic as some companies in online business are becoming more prominent than others. Target and Walmart have also increased in size. Best Buy has changed its focus with its conversion into a company that leads with personal service in online plus store hybrid retail and a focus on seniors and older people for healthcare service and product delivery. Companies are changing the way they run or getting a new life in remaking their business. This is also a time when other aspects of business such as social media are becoming evident. Subtle aspects such as reports of higher rates of mental depression through use of social media platforms. There is also the awareness that information technology companies in Silicon Valley generate most of their money in advertising and this advertising of $100 billion is only a small fraction of the $12 trillion U.S. economy. Should Silicon Valley based in California decide priorities on where capital allocation should go through the part it plays in moving startups based less on America's priorities than other considerations. Healthcare, education, cities, and infrastructure have not received funding they need and capital allocation by financial markets has failed the American people, as it has failed in Europe and other parts of the world for similar reasons. This has hit hard communities and people across the U.S. and Europe and also in Latin America, Africa and Asia, with the loss of manufacturing to China and other countries from the U.S. India and Europe. ...

Layoffs at Microsoft, Amazon and Google are offset by more hiring. So that the companies are smaller by a small margin in 2023 compared to 2022, yet way larger than 2018. WSJ looks at the growing size of these companies. At Microsoft the headcount is 101,000 outside the US, a 70% increase since 2019. Apple's 161,000 employees are much higher than the 137,000 in 2019. A small trimming of employees only took down 3000 employees.

With a redrawing of the tech map and where the jobs are tech jobs shift to mainstream manufacturing, health, banking and retail, says this report in the NYT. These companies invest steadily in tech jobs but did not go into manic hiring sprees in the way Amazon or Alphabet once did. Overall employment in tech occupations increased to 6.39 million in November 2022, a 12% increase over the prior year. Chase, Amex, Nike, Wal-Mart and General Motors offer more stability for tech workers. Overall US tech workers increased from about 3 million workers in 2000 to over double that in 2022. Unemployment is at 2% for tech workers compared to 3.7% for workers overall. The problems at Alphabet and Amazon and layoffs are making it easier for mainstream retail and banking companies to hire tech workers. Chase Bank alone has over 50,000 tech workers.

Microsoft's Satya Nadella got his start at age 24 at Bing search engine. He is now 56 years. During this period he worked with both Bill Gates and Steve Ballmer who succeeded Gates at Microsoft. He is now remaking the Bing Search engine by using AI. This has happened since 2018 when he met Altman at the Sun Valley Tech conference in Idaho. He invested $1 billion in Altman's OpenAI, and has recently brought in Suleyman of Inflection who is a competitor of  Altman's OpenAI into Microsoft with the idea of setting up an internal AI business as well. To do this he has invested $10 billion in advanced AI chips that he has bought from chipmakers which have reduced the capital available for Microsoft's other businesses. This WSJ report by Dotan and Jin says Altman started his venture because he did not want to let AI to be led by Google silently developing its own version and doing leapfrog over competitors. A At this point in 2024 Google, Facebook and Amazon are building their own AI talent and making large investments in the chips that support AI. It is rapidly becoming an oligopoly of a few tech companies that makes deals among themselves for strategic advantage and protect themselves from public or government regulatory scrutiny. The controversy surrounding the firing and rehiring of Altman at OpenAI has brought new scrutiny from the FTC. The monopolistic behaviour of tech companies and their splitting the tech market among themselves as Google and Apple have done show the need for government action to prevent a repeat of this in AI. And to take action to break up existing monopolies in Search engines and in the Internet as Theodore Roosevelt did at the turn of the century for the oil business, breaking up Rockefeller's Standard Oil and Esso. Only when that happens can the true potential of the Internet be realized for Education, Health and other fields. Who can say that the iPad or iPhone or Google's Search engine has increased global literacy or American literacy? By freeing up these technologies- that belong to the people of America and the world- for education, health and other fields of human development mankind can advance once again. By regulating provide the ground rules for good use instead of the current danger of the Internet acting in ways to reduce public knowledge to levels that cannot sustain democratic process, and create stratified society where each group only sees what it has seen before and does not explore the world or knowledge in all its variety, all its ability to surprise us with new discoveries. ...

With the introduction of the iPhone 4S, Apple announced the iPhone 3GS will be offered free, and the iPhone 4 for $99. This puts Apple iPhones priced to compete with smartphones in the middle and lower price ranges in the market. The free iPhone is a model first introduced in 2009. As the expansion of the smartphone market is now ocurring at the low and mid price ranges, companies making smartphones using Google's Android software and Blackberry's RIM are targeting this market. In the U.S., as of the end of July 2011, 82 million Americans owned smartphones, increasing 10% from the prior quarter, according to comScore. 42% of U.S. smartphone users use Android phones, only 27% use Apple phones, as of the end of July 2011, because of the price difference. In India Apple iPhones have barely made a dent because of large price differences. Rapid growth expected in emerging markets will also make this low end of the smartphone market attractive for Apple.

Walt Mossberg, who writes the Wall Street Journal's consumer technology review section, watched Steve Jobs up-close over the years since 1997. They met one-on-one for product introductions, long discussions about the industry, and recently after Jobs illness, at his home in Palo Alto. Mossberg describes a long walk to a nearby park after Jobs had undergone a liver transplant. It provided an insight into the man Steve Jobs was. Persistent- he called Mossberg for 4-5 straight weekends during the dark days of 1997-1998 to convey his vision of Apple products or discuss aspects of reviews. Patience and optimism about the future- Jobs always maintained a positive tone and a vision of what could be in the digital revolution, and Apple's role in it in these discussions. There is the opening of the first retail store in the Washington D.C. area, and Jobs patiently handles Mossberg's incredulity about Apple and its inexperience with retail stores. And Jobs saying that he had taken a serious interest in the details- down to the translucency of the glass. There is the meeting with Bill Gates at the fifth All Things Digital Conference, when both made their appearance together for the first time and Jobs hands a cold bottle of water to Gates. By this time Jobs had already come to the conclusion- as he once said after accepting a $150 millon investment from Gates in 1997-1998- that it was no longer true that Microsoft had to lose for Apple to succeed....

David Gelernter, Yale professor of computer science, says above all things Steve Job was designer-in-chief. At his Stanford commencement address in 2004, Jobs recounts his experience in a calligraphy course at Reed College as one of the singularly important experiences of his life, and something he carried over to the the revolution in portable devices- portable Macs, iPod, IPhone and iPad. The search for and building of elegant, easy to work, fun to use devices. Job was able to grasp the potential of such devices, says Gelertner, from his very first visit to the Xerox research labs in Palo Alto in 1979. In doing this he gives credit for long forgotten pioneers of the personal computer, who were just as important perhaps even more so, Douglas Engelbart and Alan Kay. At Xerox, Kay built on the earlier innovations of Engelbart. Engelbart was first to develop the mouse, onscreen window, and the concept of computers doing more than just computing, such as controlling machinery, doing everyday stuff, and doing things with pictures. Xerox's corporate executives failed to grasp the significance of the developments in their labs. Jobs grasped this rightaway and put all his efforts into developing the Apple Macintosh in 1984 incorporating these ideas. A decade later Gates copied the Mac's eay to use features and created economies of scale, creating the personal computer that we know today. The internet was a parallel development during that decade after the pioneering work of Tim Berners-Lee on the worldwide web. Jobs took the experience one step further and created new devices like the iPhone and the iPad that brought mobility, ease, and refinement to the internet experience....

The different strategies of Apple and Samsung in getting to the point where the two companies now dominate the smartphone market. Whereas Apple makes only one phone, its iPhone, Samsung's strategy is to have multiple phones in each price segment. It has five levels of Android based phones, with 2-3 models in each price segment. Samsung also benefits from doing its own maufacturing. When faced with a number of technologies Samsung's strategy is to bet on all of the technologies until one of them emerges as a winner, and then concentrate resources on that technology. It uses a similiar strategy for televisions. Apple by contrast places more emphasis on original design and profit margins over sales, gaining sales without eroding margins by being the first innovator in the market. It also has its own unique arrangement for manufacturing at lowcost with Foxconn in China that supports its high margins. Apple is secretive about its designs and promotes its brand heavily with its own retail stores. Apple also uses its innovative edge as leverage to steer profits away from carriers. Analyst estimates are that carriers such as AT&T and Verizon pay about $400 per iPhone to subsidize its cost because this is the only way to get customers into their retail stores. IDC estimates are that the smartphone market is $219 billon in 2012. Both companies are very close in volume- IDC estimates Apple shipped 93.2 million smartphones in 2011, compared to Samsung's 94 million units. Apple has market share of 23.5% in the fourth quarter 2012, up from 16% in 2010. Samsung has 22.8%, up from 9.4% in 2010. Apple and Samsung have together taken 91% of operating profits of all cellphone companies in the fourth quarter, an increase of 30% from 2011, according to Strategy Analytics....
