San Francisco Frontiers - Crowds cheer pope in Paris after AI 'paradise of machines' warning

Balconies and sidewalks were decked out in the Vatican's yellow-and-white colours as the pope made his slow journey to the Notre Dame cathedral in the centre of Paris.

People rushed forward to kiss the hand of the first US pontiff before he entered the cathedral to organ music, on the first official papal visit to the European nation in 18 years.

"There he is, he's here!" one person cried as the popemobile passed by on Pope Leo's first major public appearance in the capital, under a clear blue sky.

"Look, it's the Pope, this is crazy," said another.

David Charton, 53, said he had arrived at 6 am to find a good spot after travelling all the way from Mulhouse, near the border with Switzerland and Germany.

"I'm a believer, and it's our duty to welcome the head of the Church," said the factory worker.

Monique Barusseaud, 83, was waiting with a foldable stool.

"Today, at last, I will see the pope," said the retiree from the southwestern city of La Rochelle.

Leo is the first pope to inspect renovations at the Notre Dame Cathedral following a devastating 2019 fire.

His predecessor Pope Francis -- who visited France three times, but never officially -- did not attend the Gothic masterpiece's reopening in late 2024, when then president-elect Donald Trump and billionaire Elon Musk were among the guests.

- 'Authentic secularity' -

The much-awaited parade came after Pope Leo spoke at the presidential palace on the need to safeguard humanity against artificial intelligence.

"If we are to avoid losing our humanity amid a paradise of machines invading and conditioning our daily lives, there is an urgent need for education in ethical discernment," he said beside President Emmanuel Macron.

In a time of tense transatlantic ties and as Russia's full-scale invasion of Ukraine drags on in its fifth year, Pope Leo urged the European nation to remain a "tireless champion of peace".

"In the face of rumours of war and the varied crises troubling our world, France is called to remain a tireless champion of peace and multilateralism, particularly within our beloved Europe," he said.

The pontiff's visit comes just seven months away from a presidential election to replace Macron, with the anti-immigration far right eyeing its best chance at seizing power.

In a proudly secular country that has for more than a century separated church and state, Pope Leo stressed that "authentic secularity" should not exclude religion "from the public sphere or from education".

Politicians have in recent years often invoked France's brand of secularism to justify bans on religious symbols, including Muslim women's attire, in public spaces and schools.

After France passed legislation in June granting some adult patients the right to assisted dying, the pontiff warned against turning "science and technology into profit-driven ventures promoting genetic manipulation, surrogacy, the trade in human organs or the possibility of arranging one's own death".

- Lourdes, Metz -

A million people were expected at events across Paris during the first two days of his trip, as he marked the first official trip by a head of the Vatican since Pope Benedict XVI in September 2008.

The high point of the apostolic journey will be a giant mass on Saturday, led by the pontiff at Place de la Concorde and adjoining Champs-Elysees.

Pope Leo will also visit Lourdes, a pilgrimage site for Christians worldwide where he will privately meet victims of clerical sex abuse, and Metz, near the German border, where he is to speak about peace in Europe.

Last on his agenda on Friday will be a mass prayer and hymns with 80,000 young believers aged 17 to 35 in stadium in the Paris suburb of Saint-Denis.

But while the number of infant christenings has dwindled in recent years, teenage and adult baptisms are on the rise, with thousands choosing to embrace the faith.
