Have you ever seen US GDP go up 5% yearly for several years?
Doesn't have to go up. It's also fine if they replace other parts of the economy.
The quote is about a one-time increase in growth of 5 percentage points. Not multiple years or forever.
Or obviously it can be spread out, e.g. ~1% additional increase over 5 years.
That’s the bet! last time we had that growth was for a few years during the dotcom, followed by a lost decade of growth in tech stocks
