I have no issues with the inclusion of the AI in products.

My issue is throwing GenAI at problems that GenAI was clearly not meant to solve.

If a better algorithm/solution exists, use that instead...

One thing I really like about RMAUs is that it forces people to use the correct roles.. PIM'ing to GA won't work for everything

Attackers don’t care about your roadmap slide

They care if one weak control lets them inside

Security copilot won't let you deploy Overage SCUs only...Unless you deploy 1 SCU first then turn it down to 0 after.

Nice try LinkedIn with the wrap but I'm not installing your app.

If it can run in a browser.. Its staying in the browser

I can't wait for all these browsers to add AI honestly.

Finally businesses will see the use case for a single properly managed browser and block the rest.

Top tip:

Wear your battle jacket to conferences. Then you spend more time talking to sales people about bands than their fancy expensive dashboard
