The real challenge here is that so many of the world's records have been lost and for many individuals, no records were ever created. Even if my speculation about the digitization of all the world's records were possible, genealogists would still find it a challenge to find records for every individual. Digitization alone does not provide access to the records and from my standpoint, access is a more difficult problem to resolve than the physical digitization of all the records.
As time goes on, I realize more and more each day, how limited I am by the availability of records I know exist and by the time it takes to examine those that are available. For example, here is a chart from the FamilySearch.org Research Wiki on one parish in England. I chose Fletton in Huntingdonshire (now Cambridgeshire) to illustrate the time periods and jurisdictions involved in a search of the parish records.
|Poor Law Union||Peterborough|
|Parish registers: 1604|
|Bishop's Transcripts: 1604|
|Diocese||Pre-1837 - Lincoln; Post-1836 - Ely|
|Probate Court||Court of the Commissary of the Bishop of Lincoln and of the Archdeacon in the Archdeaconry of Huntingdon|
|Location of Archive|
|Huntingdonshire Record Office|
Here is a summary of which of the records are online:

You might notice that three of the four websites referenced are paid sites. This illustrates the challenge. You might think that digitization alone will solve the problem of finding your ancestors, but the real problem is that despite digitization, the records will still be fragmented into a myriad of websites all over the world. In fact, for many people finding the records online and then gaining access to those records may present as much of a problem as finding the un-digitized records today.
