内容摘要：While the exact timing of humans’ arrival in the Americas remains contested — and may never be known — it seems clear that if the first people arrived earlier than once thought, they didn’t immediately decimate the giant beasts they encountered.

While the exact timing of humans’ arrival in the Americas remains contested — and may never be known — it seems clear that if the first people arrived earlier than once thought, they didn’t immediately decimate the giant beasts they encountered.

“China aims to lead the world in AI by 2030,” said Sen. Ted Cruz, chair of the Senate Commerce, Science and Transportation Committee. “In this race, the United States is facing a fork in the road. Do we go down the path that embraces our history of entrepreneurial freedom and technological innovation? Or do we adopt the command and control policies of Europe?”Senators were broadly sober in their questioning and united in their concern that the U.S. maintain its dominance in artificial intelligence. Lawmakers from both parties also raised concerns over cybersecurity, data privacy and AI’s ability to create content that could confuse or mislead people.

Some partisan fighting did arise. Sen. Bernie Moreno, an Ohio Republican, pressed Su and Smith on whether the Biden administration’s sustainable energy policies hindered the goal of producing more power for AI-related infrastructure.And Sen. Tammy Duckworth, an Illinois Democrat, criticized cuts by President Donald Trump and billionaire Elon Musk to federal funding for research and to agencies like the Energy Department’s national laboratories and National Science Foundation, painting them as “a self sabotaging attack.”“Does anyone truly have confidence that had DOGE been around decades ago, they would not have cut the project that created the internet as an example of wasteful, publicly funded research and development?” asked Duckworth.

But despite some barbs, the hearing maintained a low-key tenor and some bipartisan joking as lawmakers and executives discussed the potential of a technology all present agreed would determine humanity’s future.“Look, there is a race, but we need to understand what we’re racing for,” Sen. Brian Schatz, a Hawaii Democrat, told the witnesses. “It’s not just a sort of commercial race, so we can edge out our nearest competitor in the public sector or the private sector. We’re trying to win a race so that American values prevail.”

Several of the executives warned against U.S. export controls that could end up pushing other countries toward China’s AI technology.

“We totally understand as an industry the importance of national security,” Su said. But she added, if not able to “have our technology adopted in the rest of the world, there will be other technologies that will come to play.” Those technologies are less advanced today but will mature over time, she said.in five years — end the negotiations until 2027 and wait for approval from each of the EU’s 27 member countries until 2030 — which is an ambitious pledge while battling conservative opponents with public recriminations and competing promises of pay hikes.

Rama, 60, who secured the start of EU membership, highlighted achievements in infrastructure and justice reform in his campaign.

The Socialists say they will accelerate aand increase foreign visitors from 10 million arrivals in 2024 to 30 million by 2030, by diversifying destinations through the expansion of infrastructure projects. Rama has also pledged pension and pay hikes.
