By the time we have walkable cities we'll probably have cybernetic legs and hover mobility scooters

Quickest thing to notice about the part of the town I'm in near the senior center, where the walking trails go through it there's SIGNIFICANTLY more seating and trash cans. There's benches spaced out around the rest of town too but honestly the buses are probably more reliable for that, unless it's a busy day or time and you have to stand there too. Downtown has a lot of public seating too but the spacing is weird and it's just a busy area where that seating might be taken, or sticky, because there's a bunch of ice cream shops over there and people dripping or spilling has become enough of an issue that it's not uncommon to see a "NO ICE CREAM" sign.

but empathy is literally impossible

Huh?

Sits on the ground

I don't know what's going on here.

Major cities are a PitA

Three minutes isn't a long walk for an old person either, unless they're pretty badly disabled or such, and at that point they'll have walkers with built in seating, or be in a wheelchair with a carer already.

I agree we need more public seating, and more that's comfortable and not designed to contort you in weird ways. But seats every three minutes walk? That's kinda insane :-P
