That claim isn't just a lie regarding the consumer preferences, but also the technological developments. It's not impossible to predict at all; when talking about long term limits the picture is pretty clear.

We already know that a fiber can carry 20 terabits per second, because it's already doing it in backbone ISP connections today. If necessary and economical this can be done towards individual houses in 40 years. The only hard thing to predict is the speed of price decay. But as a sort of anchor value I can tell you a pair of transceivers for 100 Gigabit per second over 10 km can be bought for 500 USD right now.

We also know that radio links are fundamentally limited by the Shannon limit, which relates the possible bit rate to the spectral bandwidth given a noisy channel (like our atmosphere). Maybe you'll get a few dozen GHz of spectrum usable from space, in the mmWave region. And with that you probably reach dozens of gigabits per second. There is still a lot more to be had than today, sure, but with a definitive limit not too far off.

To be clear the Shannon limit applies to the optical transport in fiber too, but there we are working with around 4500 GHz of usable spectrum just between 191.5 THz and 196.0 THz (the conventional band for DWDM), way way way more than radio will ever have by the nature of things. And people are expanding that range downwards to 184.5 THz already, and that's in the market, not just in research.

Oh if it’s impossible to predict long term technological developments then why are my fucking tax dollars subsidizing data centers.

Two faced fucking ass politicians

I hate gigabit internet. It's fast and gets everywhere.
