Training the AI is the hardest part of developing a robot. In case of cars, it needs lots of driving videos in different scenarios. In case of robots, it needs robot hands doing various tasks and sensor I/O associated with them.

The first thing Tesla built for Optimus is ability to teleoperate the robot. Since the robot is near identical in physical features as a human (similar strength, joints, degrees of movement of limbs etc.) teleoperating optimus is trivial for trainers.

Then these trainers teach robot how to perform actions, and that high quality vision + sensor actuation data gets captured for training AI to do the job as well.

I see these other companies (Boston Dynamics etc.) doing weird robot designs and I can't see how they'll generate high quality data for those robots.

Rescue craft is not a thing. It's a very unusual situation caused by unexpected, safety-critical failure in boeing craft.

Maybe it will become a thing in future, but I'm guessing it will be a long time before boeing shuttle flies again.

The "flying unsuited in cargo" part is probably because there might be a dragon capsule already docked to ISS. In case of a health emergency for either crew, the cargo section would be an uncomfortable but safe ride.

(The shuttle's cargo section is designed to secure cargo of various sizes and fitting a human safely in it probably won't be that difficult.)

However, if the astronauts end up staying up there longer, a space suit could be sent up with a new dragon launch making for a more comfortable / safer option.

The "Boeing Blue" spacesuit is a traditional (aka legacy) design that has 3 connectors that connect to spaceship's seat: 1. Life Support: for ventilation and climate control 2. Communication: for audio and data 3. Power: to power all suit's computers and other electronics SpaceX has a single umbilical connection for all 3 systems. Note that both suits have diagnostic tests / suit pressurization tests etc. to ensure that all systems are green as part of an umbrella of safety checks. SpaceX suit is simply more advanced. Note that this situation is quite unusual because astronauts usually don't return on a different spacecraft than the one they flew up in. So, suit compatibility isn't really a design goal.
