No, fuzzy logic won't make your washing machine better. Yes, you can implement some stuff in fuzzy logic.
Ideally, people that do nothing but tick off boxes in their mental buzzword checklists should not even be allowed to attend the pitches, and thereby waste other people's time by forcing them to hack around the unrepentant ignorance. But they that have the gold, make the rules.

There's really not, but it might make you feel better to think there is.
We have already seen this with things like offshoring.
A few big name companies did the numbers and found they could save some on moving their production somewhere else.
Then came a rush of companies that made big that they had offshored who knows what, simply because that was what the stock market expected of a would be forward looking company.
The basic problem is that these decisions are not done based on what is good for the company long term, but what is good for the stock price short term. And in large part because CEOs are paid in stock options, and can be ousted by activist stock owners.
They probably decided they wanted to be part of that future market about AI and therefore want to invest in AI/ML startups. Someone sold your company internally as being a nice fit for the AI portfolio, but when you answered the question about ML with "No" the door was shut.
From someone who makes large trade deals as his daily business, I learned "Never say 'No'" (during a negotiation). In most cases, it is better to be diplomatic. So might have been better off with something like:
'So far we had decent results without ML, but we are constantly evaluating options to improve our technology, which includes optimizations based on machine learning.'
That way, some might hear '[...] includes optimizations based on machine learning.', while you just said 'we do not use machine learning' ;-)
