No.
If the trend continues.
Exponential growth, a/k/a constant periodic percentage growth (per day, month, year, etc.), increases rapidly. Differences (or errors) in magnitude measurement disappear rapidly: a factor of two in a single generation, a factor of ten in about three generations, a factor of 100 in less than 7, a factor of one thousand in fewer than 10.
What matters is that the growth rate continue.
Which of course, it usually doesn't. Most growth trends follow a sigmoid rather than exponential curve (initially), or more complex longer-term dynamics.
The point of your infamous horse quote was less to show that the Earth would be covered in horses (or their effluvia), than that the observed current trend could not reasonably continue. And as some of us are aware, it didn't, due to the adoption of ... the petroleum-fueled automobile ... which has some bearing on this particular HN post itself.
Had the automobile not come along, or petroleum reserves proved much more limited as was widely believed at the time[1], large horse-congested cities such as London, New York, and Chicago would likely have seen sharply slowed or even reversed growth under negative hygiene pressures. It was the multiple factors of growth in fossil fuel use (displacing horses, and their effluvia), development of sewerage systems, solid waste disposal, food safety and purity, refrigeration, and public health which turned cities from death zones to attractive living places, rather than merely drawing desperate immigrants through high wages amidst rampant rural and foreign poverty.
But the point remains that the sustained growth rate matters far more than the starting point.
2030 is three and a half years away. That's soon.

1. It wasn't until the 1930s with the discovery of the East Texas Oil Field in the US and of vast fields in Saudi Arabia that it seemed likely that oil was more than a short-term resource. In marked contrast to, say, the short-lived Indian natural gas boom of the late 19th and early 20th centuries: <https://en.wikipedia.org/wiki/Indiana_gas_boom>. Daniel Yergin's The Prize is an excellent history of the industry's growth, though I disagree strongly with the author's strong allegiance to it.

Exponential Growth in datacenters is extremely unlikely.
I doubt it could be sustained for half a generation before Colo became cheaper than air.

If you add "Sustained" in sure, but its unsustainable, leading back to the starting point mattering more than the rate.
Theres not enough RAM for now. You double colo space worldwide, and there's simply not going to be computers to put in there. That's just the canary, there's indicators of other component shortages. But like, pretending this is exponential will quickly burn out other things. Steel. Powder Coat. Fibre.
Not to mention that funding for data center expansion is already drying up and projects are being cancelled. I honestly dont believe in a single local project that isnt branded NextDC or Equinix. Outside of them I wouldnt be surprised if 90% of projects failed to materialise.
I dont know what world you live in where you think theres an exponential Data Centre growth going on but its not this one. We are already up against the wall. I guarantee you will have a new industry you just learned about to get anxious about by 2030. Just how Bitcoin didn't exponentially grow to consume the whole planets energy supply by 2025 as predicted.
