anything going out there for those long journeys would/should be big, so there would be enough walls, storage of supplies, reaction mass tanks, etc. to provide significant protection.

Not really. Galaxy is 100k ly across, you can make the journey end to end in 1mil years at 10% light speed. Obviously talking about probes/tech, not "biologicals".

1mil years is really short in the grand scheme of things.

		>Obviously talking about probes/tech, not "biologicals". human brain has 100T synaptic connections. We already have 2 trillion parameter AI models. Parameter count grows more 3x per year. It means that in 4 years we'll have 100T model. My point here is that by the time we have probes to send even to the closest star, the biological brain would be the inferior option, and most probably we'd even be able to upload, just as fun small companions-observers, a bunch of people brains into what by the time would be a superintelligent 100000T+ parameter AI brain of the probe.
