I also grew up on the internet, but disagree strongly: the challenge of onboarding remotely is real, and more challenging the equivalent on-site experience.

And to be very precise: I don't think that remote vs in-office onboarding is simply different, or even that it simply requires more intentional efforts, but that it is on the whole entirely more complex in non-trivial ways (in time, effort, and attention by all parties - aka: more cost).
