   Dr. Wang Chenglu, President of Huawei’s Consumer Business Software Department, recently revealed that the adaptation of the mobile version of Hongmeng OS 2.0 is progressing very well, and R&D is ready, and it is expected to be released as scheduled in December.

   He also said: "At that time, I hope that the majority of developers and friends can participate together, work together and build the Hongmeng ecosystem."

   According to the latest exposure of the digital blogger, the mobile phone Hongmeng OS 2.0 has been tentatively scheduled to open the Beta test version on December 18, and will provide upgrade channels for some mobile phone users in January and February next year, and there will be a few months of preliminary Upgrade verification, and then fully open the upgrade.

Hongmeng OS 2.0

   Obviously, Huawei is very cautious in upgrading the mobile phone Hongmeng OS. After all, such a disruptive change cannot tolerate any mistakes. It must be done slowly. Everyone must be patient and wait slowly. Maybe it will be this time next year. Complete a comprehensive replacement on Huawei phones.

   Wang Chenglu also revealed that more than 90% of Huawei models currently on the market will be upgraded to Hongmeng.

   It is reported that as early as May 2016, Huawei decided to build the Hongmeng system internally, and laid out the possible directions of the future market and technology. The core innovation is to treat individual IoT devices as different modules, and then proceed Connected because it is an operating system developed for the Internet of Everything.

   After a week of intense voting, Democratic candidate Joe Biden defeated Donald Trump and won the 2020 US presidential election. At the same time, the United States also welcomed the first female vice president of African descent, Latino and South Asian descent (Kamala Harris).

   Major US media, including the Associated Press, Washington Post, New York Times, CNN, NBC, CBS, Fox News, etc. all released election forecasts, saying that the Democratic presidential candidate Biden won the presidential election with more than 270 electoral votes.

   Currently, Biden has changed his Twitter account authentication to "U.S. President-elect", and Harris has also changed his Twitter authentication to "Vice President-elect."

   After the election results were settled, Biden said on Twitter:

   America, I am honored that you have chosen me to lead our great country. The work before us will be tough, but I assure you: I will be the President of all Americans-whether you vote for me or not. I will live up to your trust in me.

Biden was elected president

   After Biden was elected, bigwigs in the technology industry have all spoken out on social media and congratulated Biden and Harris.

   Facebook COO Sheryl Sandberg wrote a long post about the rise of female leadership. She wrote:

   Sometimes, the United States will take a big step towards establishing a government that reflects our diverse country. Today is such a day. I thought with joy that young people all over the country are watching the news today, thinking, "Maybe I can lead this country, too."

   Congratulations to Kamala Harris for this extraordinary achievement-breaking the glass ceiling and norms of the leadership-and congratulating President-elect Biden on this historic milestone.

   Amazon CEO Jeff Bezos posted a picture of Biden and Harris shaking hands after their victory on Instagram to congratulate them on their election and said:

  Unity, compassion and decency are not characteristics of the past. Through a record vote, the American people once again proved that our democracy is strong.

Biden's election as president, the US technology circle is boiling!

   In addition, the two CEOs of Microsoft also sent messages congratulating Biden and Harris.

   Congratulations to Biden on his election as President and Harris on his election as Vice President. Thanks to election officials and campaign staff for their tireless efforts to ensure that a record number of Americans vote and to count votes at a time when our country is facing challenges.

I look forward to working with the new government and the bipartisan leaders of Congress to control this surging epidemic, engage with partners around the world on issues such as poverty and climate change, and resolve domestic inequality and opportunities. .

   Brad Smith, the current president of Microsoft, is even more eloquent, writing a long blog "Building a New Bridge: Our Thoughts on the US Election", in which a Microsoft logo was placed.

   wrote in the blog:

   This year’s election day has become a long and tense election week, and many Americans are anxiously staring at the screen awaiting the results of the election. I often hear speculations from authority figures that we seem to rarely have such a divided country. If it is true, this also makes another proposition even more self-evident-if we are to move forward as a country, we must build new bridges and bridge the gap between us.

   Biden's election as president, the US technology circle is boiling!

   In addition, some bigwigs in the AI ​​field are not idle.

   Associate Professor of the Department of Computer Science and Electronic Engineering of Stanford University, Director of the Artificial Intelligence Laboratory, Chinese American Wu Enda tweeted:

   I am relieved by the results of the election and thank the many people who made the election possible. Thank you to everyone who helped with fair elections, to the media who defended the truth, and to everyone who voted or spoke to participate in this wonderful democracy.

Biden's election as President The US technology circle is boiling!

   Yann LeCun, a professor at New York University, Facebook's chief artificial intelligence scientist, and ACM Turing Award winner, posted a slightly humorous tweet and attached a video of the alarm bells ringing and cheering in Paris, France.

   Yann LeCun said:

   After Biden announced his victory, bells rang across France. In fact, I think they are more happy with Trump's defeat than with Biden's victory.

Biden's election as President The US technology circle is boiling!

   Jeff Dean, senior researcher and senior vice president of Google artificial intelligence, is more concerned about whether the visa policy can return to normal after Biden takes the stage?

   I very much hope that we can allow the United States to welcome the best and brightest students from all over the world to our colleges and universities. This has been an incredible strength of the United States for decades. I hope we can welcome outstanding students with open arms again!

   Biden's election as president, the US technology circle is boiling!

   Interestingly, a comment under this tweet stated that it has been bad for decades, and Trump just made the situation worse.

   Biden's election as president, the US technology circle is boiling!

  Francois Chollet, the father of Keras, said:

   Anyway, I am very happy to see this episode of "America" ​​ending in a comedy rather than a tragedy.

   Biden's election as president, the US technology circle is boiling!

   After Biden takes office, what impact will the technology industry have?

  The new president’s taking office has attracted much attention, but its impact on the technology circle is also worth noting.

  Especially in the United States under Trump's leadership, there are still many unsolved issues, including antitrust investigations by technology companies, net neutrality, rural broadband, and online privacy.

  According to Cnet reports, Biden’s position on these issues is mainly as follows:

  - Antitrust

   During the U.S. election campaign, the U.S. Congress launched an antitrust investigation against American technology giants. And, just last month, Google was filed a lawsuit accusing it of illegal monopoly in the field of search and search advertising.

   The antitrust investigation by the technology giants has not yet ended. How to restrain large technology companies has become one of the issues Biden needs to think about.

   Earlier, a 449-long stern report of Congress detailed the abuse of market power by Google, Apple, Amazon, and Facebook, and the report also laid out ways to curb the dominance of the four major US technology companies, which may indicate Under the Biden administration and the Democratic-controlled Congress, technology companies will face trouble.

   Obviously, the U.S. government has begun to conduct stricter scrutiny on large technology companies.

   Regarding this issue, Biden has previously stated that it is too early to discuss the separation of companies, and he prefers to restrict the power of these companies through supervision.

  - Section 230

  Section 230 (Article 230) refers to Article 230 of the "Communication Regulation Act" promulgated by the United States in 1996, that is-

   The provider or user of interactive computer services shall not be regarded as the publisher or spokesperson of any information provided by another information content provider.

  No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.

   In other words, Internet companies generally do not need to take responsibility for the content posted by users on their networks, which provides Internet companies with a legal "safe haven."

   In this regard, Biden once told the New York Times that "Section 230" should be abolished immediately.

  -He said:

   This is propagating a lie that they know is wrong. We should set standards, just like Europeans do in terms of privacy.

   In addition, during the election, the Biden team used to open Facebook for political advertising content.

  -Net neutrality

   Regarding the issue of net neutrality, Biden himself has little to say.

   However, a spokesperson for the Biden campaign said that the president-elect supports strict protections of net neutrality.

   The spokesperson pointed out in the statement:

   Joe Biden has promoted net neutrality and hopes to see (the Federal Communications Commission) take direct action to keep the Internet open and free for all Americans.

   However, Cnet reported that when Biden was a senator, he did not co-sponsor or support net neutrality legislation, including the 2007 Internet Freedom Protection Act.

   Therefore, this issue remains to be seen and studied.

  - Rural broadband

  During the campaign, Biden once stated that it is the "moral responsibility of our time" to rebuild the American middle class. He believes that the revitalization of the American countryside is the cornerstone of this effort.

   Regarding the rural economic development policy, one of his strategies is to invest US$20 billion to provide broadband access to communities without broadband. At the same time, he also called for cooperation with municipal utility companies to connect optical broadband to rural communities in the United States.

  Biden wrote in his rural policy:

  High-speed broadband is essential to the economy of the 21st century. When so many jobs and companies can be distributed anywhere, high-speed Internet access should become a major equalizer for the American rural economy, not another economic disadvantage.

  - Online privacy

  During the campaign, Biden did not mention data privacy issues too much, but from some of his speeches during his tenure as chairman of the U.S. Senate Judiciary Committee, one can still see one or two things about his attitude.

   During his tenure, Biden has introduced several bills, including the Communications Assistance for Law Enforcement Act, which made it easier for the FBI and law enforcement agencies to monitor communications.

   Now that Biden takes office, it is a foregone conclusion. As for what it can bring to the technology industry, it is still up to time to answer.

   It is worth mentioning that when everyone tweeted to celebrate, Trump also posted a number of tweets, but all of them were blocked by Twitter for "existing misleading information."
