I think it was easier to build an acceptable GUI in 2000 with VB or Delphi than it is today with our web stacks.
Looked at retrospectively, forms were just one step above green screen applications on a terminal, transplanting one set of structural idioms to another, like for like.
I see massive sea change in connectivity and immersiveness of today, but not really in what we're trying to achieve.
Most of the stuff there would be just... normal now. It's quite unusual for SPAs to have a decent consistent UX. And the slowness would never have been tolerated back in the day.
I'm not saying they were halcyon days. I'm saying that the effort to do things is not necessarily less these days, in part because we have different expectations (not necessarily requirements) today.
