@datarama in embedded systems you might be sitting closest to a sane tech architecture.
If we could reboot into a blank slate we'd probably want silicon to be very commoditized, distributed fairly evenly (not hoarded in apocalyptic datacenters mining "coin" when not mining people's souls), with lots of #opensource interoperability.
Tech as part of people's tools and furniture, with little drama. Support mostly localized (your friendly neighborhood geeks installing #fediverse upgrades etc).
