AI bubble

How much of society already depends on AI? If it goes away in some fashion, what's going to happen?

During the 2008 financial crisis the housing bubble burst because of mortgages to unqualified borrowers, complex financial products like mortgage-backed securities (MBS), and lax lending standards. So, a faulty system depending on we, the people, paying off mortgages and loans that were not being paid back. Seems a logical cause for a bubble to burst.

Before, the dotcom bubble bursted because of extreme overvaluation of companies, which were not performing up to the expectations, so the revenue wasn't there.

Now there is obviously an AI bubble as has been pointed out many many times, but currently the companies involved are still meeting their expected revenue goals (looking at NVIDIA, Meta, Google even though that is not strictly an AI-related company, their current valuation is also due to their AI developments). Of course, investing in each other and buying each other's products, causing stocks to rise, is super inflatory, but is not punished so far. It seems.

Now, a geopolitical conflict involving a certain chipmaker to not be able to produce would likely pop the bubble overnight. Given the current geopolitical situation and the people involved, this is not unlikely in the coming years. But as long as this doesn't happen it appears to be business as usual, and the AI-race will continue.

Now, comparing this to earlier bubbles, the pattern is similar. An industry is pumped to the moon, a bunch of people make an insane amount of money, the bubble bursts and most people get screwed over with a few winners. The question is always: how high will it go when the companies are profitable and how deep will the lows be?

As a retail investor who is not trading daily, this situation is extremely difficult and hard to predict when also just having a regular 9 to 5 job. I know I won't be able to predict it, so it is a risk analysis whether the current valuations will be the future lows OR if big companies with PE ratios of 50 are already a selling sign for the retail investor. This would even apply to ETFs like VWRL, since their share of NVDA is also high. The whole market will likely go down when this bubble bursts, just some companies more than others. given earlier arguments, I feel like going short here is stupid. Thereby, world governments are hedging inflation (buying loads of gold), which also has geopolitical implications. Now I believe in the mantra that time in the market beats timing the market but probably needing the money in 3 years or so, the current situation is a spicy sauce. It seems like hedging inflation (e.g. buying gold and funds like Berkshire) is not a bad move.

I keep hearing that phrase. "The AI bubble is going to burst" but...

What does it means? What impact will that have for regular people? Will it truly happen? What does needs to happen for it to burst?

I only want apps to stop embedding any for of AI as a new function, hate it
