It's always worth answering people in the level they understand the information. Sounds like a response from Michael Saylor serves best to a banker.
Here's a quick non-technical listen for next time maybe:

asa longer respnse... Yes, Ethereum uses cryptography that probably is not hackable per say, but that is not enough to guarantee profits. I agree with one of Michael's answers, which is Ethereum is a crypto platform. So if you buy ETH, you are hoping that developers will use it lots and have to pay lots of gas fees to offset too the staking rewards (ETH economics is quite complex, nevermind the hard enough transition we make to understand how bitcoin fights inflation and still promotes healthy growing economics worldwide)...
Staking offers rewards to validators, funded by transaction gas fees, and the inflation rate of ETH can be affected by the amount of staking, which influences the network’s overall supply 😵💫
Mr. banker, don't buy what you don't understand.
Furthermore, PoS leads to centralization, it's why you never play poker with someone who has more money than you: The other will take more risks for they have deeper pockets to do so and eventually take all the chips. It's a materr of time, which you buy with money. And ETH already had a head start with their premine, and current few large holders staking. Reminder: You need to be staking to really capture the ETH value, and good luck running your own node as a server class is needed to do so, another problem in ETH's decentralized plan.
Here's something I have never heard anyone talk about: ETH needs to bring in value from the real world, not just speculators, if not, how are you going to pay for the staking? Those validators want profits or they will sell ETH to make up for them, creating downward pressure on the price. So any reduction in activity is a negative. Bitcoin miners don't have this problem, as you intimately already know why.
And that's my last point. What's the upside potential of ETH? How many are competing in that class? What is the need basis of the planet to own it? What real problem is it solving for everyone? How are they going to keep increasing activity just to pay for the network? I still don't see how most of the value will sit in ETH rather than the layers above that one would rather invest in. Ulside potential for ETH doesn't seem as big as Bitcoin to me.
There's so much to learn and investigate to understand better, clearly this is the reason we can't trust our money with bankers (ever since they issued receipts for gold).
