AI investment and corporate spending is an unsustainable bubble likely to collapse like past tech manias.

  • “Most likely scenario is 90% of AI solutions, companies, and Corp spend will evaporate. Similar to past Tech bubbles.”

Bubble warnings are overblown 'FUD'; the market keeps climbing and long-term investors keep winning.

  • “Yo dawg, this FUD has been concentrated on here since last election. I’ve made more in gains the past year that I have in numerous years before. Enjoy.”

AI is already embedded deeply enough in banking and business that removing it would cause real economic disruption.

  • “If ai got turned off tomorrow it would have a significant impact on your life and it wouldn't be because you can't make dumb memes.”

    Commenters cite OpenAI's spending commitments as a risk factor

    Participants in the thread pointed to reported OpenAI fundraising and commitment figures through 2030 as evidence of outsized AI infrastructure bets, alongside individual accounts of companies buying hardware to cut AI costs.

    “Those will raise roughly 100 billion to 130 billion if they go to plan, while commitments through 2030 ... are 856 billion…”

    • The debt to long term maintainence of profitable assets is absolutely unlike anything else. At least with railways etc we could understand the potential and understand roughly what was involved in maintain growth of the capital expenditure.

    • ...sort of. The greatest contributor was a larger interest in the general public investing in stocks using money they didn't have to invest in things they didn't understand (sound familiar?). When an oversaturated American market started to lose value that lead to stock calls, the banks and the private accounts that needed the money to cover those…

    • We are using some other products(our own) to help with caching in order to let the AI do context swaps really quickly, so it might get us there. My actual expectation is that they use the on prem hardware to run predictable AI workloads against, and let humans continue to use paid products with a reduced limit. I don't know if it's enough. My main…

    Reddit thread debates whether AI spending is a bubble

    A long comment thread developed around the CNBC report, with users comparing current market and AI-spending conditions to 1999 and 1929, disagreeing on whether a crash is likely and how embedded AI has become in the economy.

    “Most likely scenario is 90% of AI solutions, companies, and Corp spend will evaporate. Similar to past Tech bubbles.”

    • I think the big difference here is that a huge portion of the population will not miss AI if it all got turned off tomorrow, or even next year. Would businesses be sad, yes. But most people would go, meh, I can't make dumb memes or pretend to know how to write code. But you literally can't lose a mortgage broker someone has to own that debt

    • Most likely scenario is 90% of AI solutions, companies, and Corp spend will evaporate. Similar to past Tech bubbles. We’ll be left with a few good solutions for code, graphics, etc. and some that haven’t been invented yet will begin to take shape. The mania will be over though. It can happen in a matter of 3-6 months.

    • My job is buying $10 million dollars worth(one time cost) of hardware to cut our AI spend by $1.6 million a month If that actually works out and they haven't grossly underestimated the amount of hardware necessary. An ROI of less than a year is fucking amazing for a business.

Still unanswered
  • Will companies' self-built AI infrastructure actually deliver the projected cost savings and ROI at scale?
  • Is the market rally being driven more by AI spending or by instability in foreign markets and oil prices?
