I hope the web isn't "the future," or at least not the entire future. We've already seen the conniptions that developers and users have suffered whilst trying to shoehorn their formats and data into Ancestry and Family Search. It would be far better IMO to have one's own flexible software so that formats and reports are obedient to one's own needs, wishes & designs.
Web data also presents issues of privacy, security and permanence which are not under users' control. Not for me, thank you.
