Rehearsals briefly resume amid uncertainty over the band's future. Following a productive meeting with Harrison, the Beatles agree to abandon the idea of a live show and relocate to their Apple Corps studio to formally record the new album.

Frontline and service workers have borne the health consequences of the pandemic, increasing racial and economic disparities. Certain robotic and AI applications are accelerating as the value of human workers is further questioned. Determining the likely areas of job growth and training needs is difficult. Post-secondary education has become more virtual and its costs, more controversial. How can we predict job growth, training needs and the role of education in order to prepare for the work of the future?

As the landscape of work shifts, do we need a drastic rethinking of social safety nets? Do businesses need offices? Is a 9-to-5 workday valid? Does the nation need a drastic rethinking of the social safety nets? Does America face a 'post-work' era, or will there be increased inequities in how we make our livings?

We’re going back to the moon. Plans are being made, hardware is being designed, built, and tested to return humans to the moon and beyond in a new era of American space exploration. This episode explores how we did it in the past, and how and why we will do it again. The moon is critical to future explorations: it will be where we learn to build sustainable colonies on other worlds.

The way that wars are fought is constantly evolving. In the warfare of today and the future, it's the push of a button rather than the pull of a trigger, bringing disorder without a single soldier setting foot on the ground. The real-world battlefield has morphed from the bloody trenches of the front line into an age of cyber warfare. From collapsing all the infrastructure of a country to changing minds for elections, any threat you can imagine can be done.

Space. Gone are the bayonets and pistols, the bows and arrows, the slingshots and stones of past warfare. Now, we have pushed into the outer limits, into a vast frontier, well beyond earth's atmosphere. Human beings have long contested the domains of air, land, and sea. Now we are racing toward a new domain. How we use space will decide our Earthly fate, a future determined not by any previous war.
