I'm standing next to a man, each of us holding a glass of El Enemigo. Mine is half empty, his half-full. He's a bit taller than me, but otherwise we seem to be getting along just fine. We have paused our conversation, entranced by the dance.
Two people in front of us move as if pulled together by invisible gravity, surrendering and resisting at the same time. One leads with subtle pressure and direction; the other answers instantly, their bodies staying close enough that every shift of weight appears shared. Their legs alternate between deliberate steps and intricate weaves. They seem to continue our conversation, only now it is charged with tension — pauses held just long enough to feel dangerous, then broken by swift pivots and dramatic turns.
As the woman's feet trace a figure-eight pattern across the floor, a question pops into my head: What do the Eiffel Tower and tango have in common?
I keep it to myself.
Part of my brain says, Give me a break. The other part starts answering anyway. Both are cultural symbols — perhaps even the souls — of two great cities: Paris and Buenos Aires. Both emerged at the end of the nineteenth century and were initially unwelcome, dismissed as scandalous and vulgar. Prominent intellectuals denounced the Tower as a disgrace to "French taste," which at the time (and perhaps still, if you ask Parisians) was synonymous with good taste. Tango could not escape the label of bad taste either, associated with delinquency and low-life bars. Yet despite vigorous opposition, neither merely survived; both became mythical.
On my second day in Buenos Aires, while heading to Palacio Barolo, I was discussing tango's history with my Uber driver, who happened to be a tango instructor. As we passed a mural of Che Guevara, I borrowed a line from Mayakovsky's propaganda poem — "When we say Lenin, we mean the Party; when we say the Party, we mean Lenin" — and plagiarized it on the spot:
"When we say tango, we mean Buenos Aires; when we say Buenos Aires, we mean tango."
I shared the source of the quote. The driver laughed and told me about a small milonga — a tango gathering — scheduled for the following night.
That's how I ended up here talking with Bruno (his name was easy to remember — I thought of Giordano Bruno and the flames; naturally I didn't share this association). He approached me and pointed to my shirt. I suppose I did wear it on purpose. It depicted a gallant man in a white shirt executing a tango move with a bodacious female android clad in steel. It said: "It takes 2-2 tango."
"Do you think this will ever be possible?" he asked.
"Well, let's dance with that question," I answered.
"That's a very tango response," Bruno smiled and offered me some wine.
After the first glass and some deliberation, both of us agreed that from a purely mechanical perspective, an AI-powered humanoid robot with synthetic muscles and advanced neuromorphic sensors — essentially an artificial nervous system — could eventually dance tango as well as, if not better than, most humans. It could maintain perfect posture, have superior proprioception, calculate balance hundreds of times per second, execute pivots with millimeter precision, and never get tired. A robotic follower could detect tiny changes in pressure and weight transfer far more accurately than a human dancer. In that sense, AI might become a tango virtuoso. This is where we paused, mesmerized by the dancers in front of us. They were not just good — they were extraordinary.
Tango is a strange beast. Unlike ballroom dances that emphasize predefined patterns, tango lives in the spaces between movements. The difference between a decent and a truly great tango dancer is not merely precision of movement — it is the ability to feel one's partner with hand and heart. In less poetic terms: to read another nervous system in real time.
Humans do this through a collection of biological hacks: from tiny shifts in muscle tension and changes in breathing, to micro-adjustments in balance and a sense of their partner's emotional state leaking into posture. I learned from my Uber driver that an experienced tango dancer can often tell whether their partner is nervous, distracted, playful, exhausted, or deeply connected — without a word spoken between them.
Ironically, an AI robot equipped with electronic skin and specialized sensors embedded in its fingertips — measuring pressure, texture, temperature, and even slip — might detect all those signals more accurately than a human. The challenge isn't sensing them. It's experiencing them.
The male dancer suddenly stepped into the woman's space, causing her leg to sweep outward. Bruno and I exchanged glances. The move — often called a sacada — required razor-sharp spatial awareness and timing. The leading partner had to calculate exactly where the follower's weight was, while the follower must respond in the moment, without anticipation. Get it wrong and you end up on the floor.
I held my breath. The dance went on. When the man paused mid-tune, I wondered how his partner could know for certain whether the stillness was intentional. I myself was puzzled: Was he inviting her to decorate the step? Was he uncertain? Was he listening to the violin?
What would a robot in her place think? Probability of intended pause: 97.3%. Executing Optimal Romantic Response Algorithm. Technically impressive — but by no means felt.
When the music ended and the applause quieted, I shared my thoughts with Bruno. Then it was my turn to challenge him: does tango require genuine emotion, or merely the convincing appearance of emotion? Actors cry on stage without living the tragedy. Musicians perform heartbreak they are not currently experiencing. Is tango similar?
"Well," he responded, "first of all, we dance not just for dance's sake, but because we want to connect with and feel another human being. Even if you could dance with a perfect machine greatly in tune with your physiological responses, it wouldn't beat a real human connection. Secondly, tango is a conversation. When you entered this conversation, were you absolutely certain it would work? Did you know for sure where it would take you?"
"No," I replied. "You can never be certain."
"So maybe that is the answer. Because a machine never feels uncertainty — and tango seems to thrive in that tiny gap between certainty and doubt. That's where the tension lives. That's where the magic lives."
We drank to magic. There is a perfect moment in any conversation that calls for the suspension of further questioning. We had reached it — but Bruno was a rebel.
Before we parted, he tapped me on the shoulder. "So we don't have to worry about the future of tango, my friend — but that doesn't mean we don't have to worry."
"About what?" I asked — and for some strange reason, an image of Giordano Bruno burning at the stake flashed through my mind again.
He smiled sadly. "About why someone would be building technology designed to replicate and replace us."
Walking back to my Airbnb through a dimly lit street, I grappled with Bruno's question. It followed me all the way to the door.
The more I thought about it, the more I wished I'd had another bottle of wine waiting at the apartment. Something softer. Esfuerzo El Amigo would do.
