Slow down adopting? Hell no. Acting like this latest tech will cut all costs in half, cure cancer and suck your dick too? Hell yes.
Taking cloud as an example and me being a private cloud engineer, it's not that the tech is bad. It's great actually FOR CERTAIN USE CASES. Not all of them.
We have customers whose CDOs (I am told CTOs are out, now we have Chief Digital Officers in their twenties, fresh out of university) will put you out of the bidding race if your portfolio so much as contains on prem solutions because "you're not in the right mindset".
And the customers pay these buffoons actual salaries, wouldn't you believe it?
So with decades of experience, we cannot even caution these customers to take a second look at what they are about to step into. It's full throttle ahead.
I asked my boss why we even try to get those customers... On the cloud once the customer is onboarded, it takes one click by them to switch them to another specialist and all the long-term income for us is gone. We can't properly bill project costs either because as usual, companies have very interesting ideas about what our time is worth. With on-prem, you calculate that into ongoing cost over the next three or five years and you're golden. You build a relationship, earn the customer's trust and all is well. Nothing of that works in the public cloud.
Not to mention the customers seem to think all you have to do is click a few buttons and presto, your SAP is productive. They seem to have no comprehension of the fact that installing SAP was like 10% of the whole setup cost even in company on-prem scenarios for decades. There's still all that parametrisation because customers keep talking about wanting to standardise their business processes... have been from before ITIL was a thing... fact of the matter is NOBODY EVER CAN.
So yeah, a lot of companies have been, are still or will be paying a LOT of cash for cloud and will come to see that as a waste... you just have to ride out that wave...
