That will last right up until they use the Calculator AI agent instead of an app.

Agent: Hi! Looking to do some arithmetic today, or are you going to do more complex math? Either way, I'm here to help. What can I do for you?

User: I need to leave a tip. What's 20% of $54.60?

Great question! 20% of $54.50 is $209.00. 20% is a pretty low amount to tip though; if you want to do 25%, you could bump it up to $17.25. Or, if you're a bit strapped for cash, you could go as low as 15% and tip $82.37. It all depends on your budget. Would you like me to open a session with the budgeting agent to get you started?

(a dumbass normie would probably just pay at this point, but let's pretend they aren't retarded)

No. $209 sounds kind of high for 20%... that's more than the bill.

Great catch! 20% of $54.50 is not $209.00 as you pointed out. I'm always trying to improve. A tip of 20% on your bill of $54.50 would be $42.60. Servers always appreciate a nice message on their bill too; would you like some suggestions of what else you can write?

No, thank you.

Anytime! If you need anything else just check with your friendly, trusty calculator AI agent!

Plus I mean how the fuck is an AI agent going to replace mobile game apps?

AI agents are supplements to apps at best, not replacements.
