| The argument made for humanoids is they are best equipped to work with human tools, in human environments. People may feel more comfortable interacting with something that looks like a bit like them. And of course, they look great. | The argument made for humanoids is they are best equipped to work with human tools, in human environments.

| The robotics behind Optimus look sound - Tesla is not exactly a novice at all this - but, Mr Nicholson says, by its release, the machine will have evolved into something physically more practical. | The robotics behind Optimus look sound - Tesla is not exactly a novice at all this - but, Mr Nicholson says, by its release, the machine will have evolved into something physically more practical. |

| In my job, I have seen lots of robots - all shapes and sizes - designed to clean, care for the elderly, teach, perform surgery, work as receptionists and tour guides, play Scrabble and chess, sing and dance, mix cocktails, pack shopping, deliver groceries, have sex, perform search and rescue and build cars. | In my job, I have seen lots of robots - all shapes and sizes - designed to clean, care for the elderly, teach, perform surgery, work as receptionists and tour guides, play Scrabble and chess, sing and dance, mix cocktails, pack shopping, deliver groceries, have sex, perform search and rescue and build cars. |

| But what the sci-fi films fail to show is all the wires, the pre-programming and the very brief battery life. As I discovered when trying to film them, early football-playing robots could last for only 10 minutes. | But what the sci-fi films fail to show is all the wires, the pre-programming and the very brief battery life.

| I have had excruciating "conversations" with conversational robots, watched many devices fail to complete the tasks they were designed for, and seen the panic in the eyes of the executives in the room when a developer brandishing a bunch of wires says: "We just need to reboot." | I have had excruciating "conversations" with conversational robots, watched many devices fail to complete the tasks they were designed for, and seen the panic in the eyes of the executives in the room when a developer brandishing a bunch of wires says: "We just need to reboot." |
| But robots have advanced considerably faster than humans in the past decade. The robots of 2022 are far more skilled than those I first saw, in 2008, whereas I have acquired little more than a few grey hairs. | But robots have advanced considerably faster than humans in the past decade.

| Time and time again though, the most impressive performers tend not to look like people. Precision-surgery robots, warehouse robots, window-cleaning robots - none of them is remotely humanoid. | Time and time again though, the most impressive performers tend not to look like people.
