So... I don't think this is certain. A surprising number of people pay for the ChatGPT app and/or competitors. It's be a >$10bn business already. Could maybe be a >$100bn business long term.
Meanwhile... making money from online ads isn't trivial. When the advertising model works well (eg search/adwords), it is a money faucet. But... it can be very hard to get that money faucet going. No guarantees that Google discover a meaningful business model here... and the innovators' dilema is strong.
Also, Google don't have a great history of getting new businesses up and running regardless of tech chops and timing. Google were pioneers to cloud computing... but amazon and MSFT built better businesses.
At this point, everyone is assuming AI will resolve to a "winner-take-most" game that is all about network effect, scale, barriers to entry and such. Maybe it isn't. Or... maybe LLMs themselves are commodities like ISPs.
The actual business models, at this point, aren't even known.
If the chat bot remains useful and can execute on instructions, yes.
If we see a plateau in integrations or abilities, it’ll stagnate.
Not necessarily. Even the original gold rush pickaxe guy Sam Brannan went broke. https://en.wikipedia.org/wiki/Samuel_Brannan
Sam of the current gold rush is selling pickaxes at a loss, telling the investors they'll make it up in volume.
If you sell your pickaxes at a loss to gain market share, or pour all of your revenue into rapid pickaxe store expansion, you’re going to be just as broke as prospectors when the boom goes bust.
So maybe if the AI pickaxe sellers get divorced it could lead to poor financial results, but I'm not sure his story is applicable otherwise.
Its products like this (Wells Fargo): https://www.youtube.com/watch?v=Akmga7X9zyg
Great Wells Fargo has an "agent" ... and every one else is talking about how to make their products available for agent based AI.
People don't want 47 different agents to talk to, then want a single end point, they want a "personal assistant" in digital form, a virtual concierge...
And we can't have this, because the open web has been dead for more than a decade.
