Ofc Sony would need to start from scratch but they could absolutely do it. Assuming they want to keep the outside dimension and material exactly like an old one, they would have to design it kinda in reverse. But the idea that the manufacturing tech has been lost is ridiculous. Sony still make tons of stuff that is electrical and mechanical. Most prominently cameras and lenses. They have tiny motors in them and tolerances are much tightener in these than in a Walkman type device. The real reason why they "can't" do it is cost. They can sell a camera for $3000 USD (or much more even) and a high end lens too. But no one wants a $1000+ USD Walkman.
