I don't think he means to be a wet blanket, he just comes from the perspective of a professional IT guy.

As a profession they have become far too used to using "cloud" services.

Its easier, more comfortable, easier to scale (for centralised solutions) and no one got fired for using AWS or other "cloud" based solutions.

But what is sacrificed is control, independence and higher costs than buying and running you own equipment.

There are also substantial dis-economies of scale with massive data farms - George Gilder has written about this in "Life After Google".

Also there is a loss of hardware technical skills, although @themarkymark is impressive this regard.

Now the chickens are coming home to roost for those that want independence and free speech.
