There’s no textbook for Data & AI Management that isn’t already outdated. The discipline is written quarterly by the practitioners in the field. 

I had the pleasure to lead the Certified Data & AI Management Officer training course at Hilton Hotels in Vienna  with Business Circle  certified by Austrian Standards. 

We took care to bring together a diverse set of lecturers to share their practitioner insights to a select group of course participants—also practitioners.

Some words of praise and recognition for the lecturers:

—Mario Meir-Huber  is the person to talk to when it comes to data products and it's always a pleasure to work with him
—Shahanaz Müller and Sascha Jung  are two expert Deloitte  partners who are among the top of the top in Austria in their fields
—Pascal Schmieding  is CDO of Santander Österreich  , well known in the community and brings a wealth of experience to everything related data management
—Alin Kalam  is an expert trainer in data analytics and a recognized leader in insurance and banking
—Sabine Gromer  is among the absolute elite CxO executive coaches in the German-speaking countries
—Eevamaija Virtanen  brings globally recognized expertise on the technology and human side of AI & data
—Marvie "Marvs" Demit  is pushing forward innovation with AI governance frameworks
—Rudolf Mayer  is a data analytics and data science expert with vast research and teaching experience
—Chris Tabb  is universally acclaimed as knowing how to show business value in data
—Christoph Praschl  and Damir Trtanj  bring extensive energy sector and leadership experience in large-scale data initiatives
—Ole Olesen-Bagneux needs no intro as one of the leading metadata experts globally and he recorded a data catalogs deep dive for this training course—Last but not least, special thanks to my own Specific-Group Austria  team Dr. Nikolaus Lipusch , Dr. Vadim Savenkov  as well as our GRC lead Mag. Dzevad Mujezinovic, CIPP/E, CISM  for providing their valuable teaching contribution to the group

Thanks to Markus Eigner  and Anna Maria Scherfler  and Business Circle for the organization!

P.S. We also did a separate AI training workshop with the brilliant Eevamaija Virtanen at our Specific-Group Austria office. Thanks to Eeva for making it all the way from Finland to Vienna!

AI infra bubble aside, CFOs know: AI profitability must be viewed as a return on overall business digitization *risk taking*, not a return on *basic chatbots*.

We do chatbots for clients. They are cool and if you don’t have one for the typical use cases by all means get one. But neither at this point nor in the past is this what people meant by saying “transform your business with AI”. 

Look. Removing FTEs with AI is cool but not really that cool (unless you’re in PE and chasing short term wind-down and cashflow optimization in which case at least you’re honest about what you’re doing).

BUT STOP. “Freeing up FTEs’ time for them to upskill and grow” -- we all say this in board decks, but is it real? The actual goal shpuld be:

-improving outcomes for your clients without them feeling you’re cheaping out, 
-growing your business and 
-seeing cashflow and profitability metrics fly 

All of that due to real process redesign that reduces operational variance. And all of that takes *risk taking* and THAT is what it’s about.

So my friend Carly Taylor’s $13,3B ABS point hits different when you realize most of us are seeing people doing chatbots in the field while calling it “AI transformation”.

Happy weekend everyone.

My thoughts on the AI bubble…

AI is not profitable yet. 

Big companies, like Oracle, and small companies, like Lambda, are borrowing money to fund their AI ventures. 

If AI becomes profitable, a lot of this debt will be paid back. But even if AI becomes profitable, some companies will fail, and some will succeed. This is normal. 

However, if AI fails to become profitable, asset backed securities (sound familiar? Think 2008 housing crisis) that are propping up some of these AI companies also fail. As companies default on their loans, these ABS will become devalued and can trigger other defaults. 

About $13.3B in ABS have been created and issued as companies race to build data centers. 

How widespread the effects of default could be depends on how this debt is being traded and who is holding the bag if things go south. 

Making AI profitable should be a key concern for everyone involved. But as we rob Peter (massive layoffs) to pay Paul (fund AI), the idea that consumers will consume enough for AI to be profitable seems pretty far fetched. 

I do believe there is a path forward for AI to become profitable, but too many AI strategies are to layoff employees to fund simple (and, quite frankly, unimaginative) chatbot projects which are NEVER going to move the needle towards profitability. 

Profitability requires novelty and innovation.
