Hm, just the fact that you mention the dead internet theory in every second post does not make it more likely. Yes, there is bot activity, but it is not the majority of meaningful content, like here on Hive. We have all these tipping bots, but people simply ignore it.
If an application is overtaken by bots, there is an auto-regulation. Like in Splinterlands: the bots took over and as a consequence the game is not as attractive anymore for humans, hence the collapse of the whole tokenomics (this is a bit simplified).
And "paying for cloud services" is not particularly exciting. Every smart contract is able to automatic payments. I am still waiting for some real interesting stuff.
