Well, it seems the AI bubble’s nearing its end - the Financial Times has reported a recent dive in tech stocks, the mass media has fully soured on AI, and there’s murmurs that the hucksters are pivoting to quantum.

By my guess, this quantum bubble is going to fail to get off the ground - as I see it, the AI bubble has heavily crippled the tech industry’s ability to create or sustain new bubbles, for two main reasons.

No Social License

For the 2000s and much of the 2010s, tech enjoyed a robust social license to operate - even if they weren’t loved per se (e.g. Apple), they were still pretty widely accepted throughout society, and resistance to them was pretty much nonexistent.

Whilst it was starting to fall apart with the “techlash” of the 2020s, the AI bubble has taken what social license tech has had left and put it through the shredder.

Environmental catastrophe, art theft and plagiarism, destruction of livelihoods and corporate abuse, misinformation and enabling fascism, all of this (and so much more) has eviscerated acceptance of the tech industry as it currently stands, inspiring widespread resistance and revulsion against AI, and the tech industry at large.

For the quantum bubble, I expect it will face similar resistance/mockery right out of the gate, with the wider public refusing to entertain whatever spurious claims the hucksters make, and fighting any attempts by the hucksters to force quantum into their lives.

(For a more specific prediction, quantum’s alleged encryption-breaking abilities will likely inspire backlash, being taken as evidence the hucksters are fighting against Internet privacy.)

No Hypergrowth Markets

As Baldur Bjarnason has noted about tech industry valuations:

“Over the past few decades, tech companies have been priced based on their unprecedented massive year-on-year growth that has kept relatively steady through crises and bubble pops. As the thinking goes, if you have two companies—one tech, one not—with the same earnings, the tech company should have a higher value because its earnings are likely to grow faster than the not-tech company. In a regular year, the growth has been much faster.”

For a while, this has held - even as the hypergrowth markets dried up and tech rapidly enshittified near the end of the ‘10s, the gravy train has managed to keep rolling for tech.

That gravy train is set to slam right into a brick wall, however - between the obscenely high costs of both building and running LLMs (both upfront and ongoing), and the virtually nonexistent revenues those LLMs have provided (except for NVidia, who has made a killing in the shovel selling business), the AI bubble has burned billions upon billions of dollars on a product which is practically incapable of making a profit, and heavily embrittled the entire economy in the process.

Once the bubble finally bursts, it’ll gut the wider economy and much of the tech industry, savaging evaluations across the board and killing off tech’s hypergrowth story in the process.

For the quantum bubble, this will significantly complicate attempts to raise investor/venture capital, as the finance industry comes to view tech not as an easy and endless source of growth, but as either a mature, stable industry which won’t provide the runaway returns they’re looking for, or as an absolute money pit of an industry, one trapped deep in a malaise era and capable only of wiping out whatever money you put into it.

(As a quick addendum, it's my 25th birthday tomorrow - I finished this over the course of four hours and planned to release it tomorrow, but decided to post it tonight.)

the key problem is they're selling Facebook and showing the investors a few broken vacuum tubes

you know that a VC tech bubble doesn't require the tech to be anything, it's just the excuse for a bubble party

extremely little of this has anything to do with a technology, six paras of ranting about "quantum deniers" notwithstanding

We literally have a generic speedup for any search. On one hand, details of Grover's algorithm suggest that NP isn't contained in BQP, so we won't be solving the entirety of maths with it. On the other hand, literally any decidable mathematical question for which you would have had to search for years for a witness, Grover can search for in days, as long as you have enough qubits. I don't claim that this is attractive to the typical consumer, but there will be supercomputing customers who are interested.

Who is "they", specifically? Neither of you actually want to talk about who's in this space for some reason. It's IBM and Google. It's incumbents that have been engineering for about two decades. It's the maturation of a half-century-old research programme. Your problem isn't with quantum computers, it's with Silicon Valley and the funding model and the revolving door at Stanford, and there's no amount of quantum research you can cancel which will cause Silicon Valley to stop existing. This site is awful.systems, not awful.tech.

BTW the top reply right now starts with "even if quantum computing isn't snake oil..." No evidence. For some reason y'all think that it's more important to be emotional and memetic than to understand the topic at hand, and it has a predictable effect on our discourse, turning thoughtful regular posters into reactionaries. What are you going to do when bullshitters start claiming that quantum computers can do anything, that they do multiple things at once, that they traverse infinite dimensions, that they can terraform the planet and bring enlightenment? You're gonna repeat paragraph 3 of 5 above, the one that starts, "it is true that we know only two useful algorithms for quantum computers," because that's where the facts start.

Also, I think that you don't understand my ultimate goal. I'm trying to push the most promising writer on the site into doing more research and thinking more deeply about history. Quantum mechanics happens to be a crank-filled field and that has caused many of y'all to write as if all quantum research is crankery. They write, "alleged encryption-breaking abilities," and you're irritated that I'm "ranting" because "extremely little of this has anything to do with a technology," while I'm irritated precisely because you think that this is a technology-neutral position and not literally part of why the TLS suite has to be upgraded occasionally.

I didn't get a message like "all quantum research is crankery" from the original post.

I think if you were trying to convince anyone to do things you'd approach it more convincingly.
