AI Productivity Masterclass at ATEKE

Great experience attending the AI Productivity Masterclass at , coordinated by Prof. John Soldatos.

A deep dive into how AI tools can reshape the way we work — from prompt engineering and smart workflows to building AI assistants tailored to your professional context.

As someone who works across IoT, telemedicine, and business intelligence, I see enormous potential in bringing these techniques into everyday business operations. The future belongs to teams that learn to work with AI, not just alongside it.

Interested in how AI can boost your team's productivity? Let's talk.

A few years ago, every business needed computer skills.
Then everyone needed internet skills.
Today, every organization needs AI skills.

Βλέποντας σήμερα τα παιδιά να λένε τα κάλαντα και παρατηρώντας τις διαφορετικές ομάδες σκέφτηκα…

🎶 Τα κάλαντα είναι η πρώτη startup εμπειρία (και δεν το ξέρουμε)

Δύο ομάδες παιδιών λένε κάλαντα στην ίδια γειτονιά.

Ομάδα Α
– ένα τρίγωνο
– «Να τα πούμε;»
– Μονοφωνία, βιασύνη, zero energy

Ομάδα Β
– στολές (ξωτικά, Άγιοι Βασίληδες)
– μουσικά όργανα (κιθάρα, καμπανάκια, φλογέρες )
– πρόβα, ρυθμός, χαμόγελο
– παρουσίαση που σε κάνει να χαμογελάς πριν καν ανοίξεις το πορτοφόλι
– Μικρό intro τύπου “Καλησπέρα σας, σας φέρνουμε Χριστούγεννα”

Ποια ομάδα θα πάρει περισσότερα;
Όλοι ξέρουμε την απάντηση.

Αυτό που κάνουν τα παιδιά της Ομάδας Β είναι επιχειρηματικότητα:
• 🎯 Διαφοροποίηση → δεν είναι “άλλα κάλαντα”, είναι εμπειρία
• 🎤 Προϊόν → φωνή, μουσική, performance
• 🎁 Branding → στολή, παρουσία, ενέργεια
• 😊 Customer experience → ο άλλος χαμογελά πριν καν ανοίξει το πορτοφόλι
• 💰 Έσοδα → γιατί η αξία φαίνεται

Ακριβώς ό,τι κάνει και μια επιχείρηση για να πουλήσει.

Τώρα φανταστείτε κάτι ακόμη πιο ενδιαφέρον:
👉 όλα τα παιδιά να λένε τα κάλαντα σαν την Ομάδα Β.

Τι θα συνέβαινε τότε;
• Ο ανταγωνισμός θα ανέβαινε
• Η ποιότητα θα βελτιωνόταν
• Η εμπειρία θα γινόταν πιο όμορφη για όλους
• Και κάθε ομάδα θα έπρεπε να σκεφτεί πώς να διαφοροποιηθεί

Ακριβώς όπως σε μια υγιή αγορά.

Στην πραγματικότητα όμως, πολλές φορές:
δίνουμε κάτι και στην Ομάδα Α —
όχι επειδή πρόσφερε αξία,
αλλά επειδή μας έπιασε η φιλανθρωπία.

Αν αυτό δεν συνέβαινε, πιθανότατα η Ομάδα Α είτε:
• θα εξελισσόταν
• είτε θα εξαφανιζόταν

Και όσο σκληρό κι αν ακούγεται, έτσι λειτουργεί η οικονομία.

Το πιο ενδιαφέρον σημείο όμως είναι αλλού:
📚 στο σχολείο δεν διδάσκουμε επιχειρηματικότητα.

Στο σχολείο μαθαίνουμε:
• να λύνουμε εξισώσεις
• να παπαγαλίζουμε κεφάλαια
• να μη μιλάμε αν δεν μας ρωτήσουν

Δεν μαθαίνουμε στα παιδιά:
• πώς να παρουσιάζουν
• πώς να ξεχωρίζουν
• πώς να δημιουργούν αξία
• πώς να “πουλήσουν” μια ιδέα

Με λίγα λόγια…
δεν τους μαθαίνουμε πώς να πουν τα κάλαντα ελκυστικά.

Ίσως αν ξεκινούσαμε από εκεί,
να μεγαλώναμε ανθρώπους που δεν φοβούνται τον ανταγωνισμό,
αλλά τον χρησιμοποιούν για να γίνουν καλύτεροι.

Τα κάλαντα δεν είναι απλώς παράδοση.
Είναι η πιο αγνή μορφή επιχειρηματικότητας.

Και κάπως έτσι…
ΚΑΛΑ ΧΡΙΣΤΟΥΓΕΝΝΑ
Χρόνια Πολλά με υγεία, δημιουργικότητα και ανθρώπους
που δεν λένε απλώς τα κάλαντα,
αλλά τα κάνουν να αξίζουν να ακουστούν. 🎶

, born in ancient , empowers citizens through participation, equality, and freedom of speech. Today, that same ethos of equality is reflected in access through the Greek National Telemedicine Network ( ). By leveraging technology to reach remote regions, including islands and mountainous areas, EDIT ensures equitable healthcare, enhances safety, and fosters professional development for healthcare workers. As Greece faces growing health challenges like diabetes and cancer, this network plays a crucial role in advancing healthcare through evidence-based decision-making.

I’m happy to share that Dextera Consulting is proud to be part of the EDIT project, working towards improving healthcare services through telemedicine. Recent studies show that telemedicine can greatly enhance care for dementia patients, providing timely access to specialized services regardless of location, reducing stress for caregivers, and offering valuable online educational seminars for healthcare professionals and patients alike.

Before Willis Haviland Carrier invented the air conditioner on July 17, 1902, it is truly fascinating to imagine the prevailing notions regarding predictions of the way of living during that era.
Willis Haviland Carrier's invention of the air conditioner not only revolutionized the way we live but also reshaped our understanding of comfort and convenience.

With soaring temperatures on the horizon, it is essential to prioritize our well-being and maintain a healthy indoor environment.
Excessive reliance on air conditioning can lead to energy waste and potential air quality issues, so here are some tips to help individuals make the most of their air conditioning while ensuring optimal air quality:

1. Temperature moderation: Instead of setting the thermostat to extremely low temperatures, aim for a comfortable and moderate setting, such as 24-26 degrees Celsius (75-78 degrees Fahrenheit). This will help save energy and reduce the strain on your air conditioning unit. And when you're away from home for extended periods of time, consider setting your thermostat 5 to 10 degrees higher than your usual comfortable temperature.

2. Maintenance: Schedule a maintenance appointment for your air conditioning system to ensure it operates efficiently. Clean or replace air filters regularly to prevent the recirculation of dust and pollutants indoors, promoting better air quality.

3. Smart use of blinds and curtains: During peak daylight hours, keep blinds and curtains closed to block out direct sunlight. This will reduce the heat entering your space and lessen the load on your air conditioning unit.

4. Strategic cooling: Focus on cooling the rooms that are occupied rather than cooling the entire house. Close doors and vents in unoccupied rooms to concentrate the airflow where it's needed most, which will improve cooling efficiency and save energy.

5. Ventilation and fresh air: It's important to strike a balance between air conditioning and natural ventilation. Open windows and doors during cooler evenings or early mornings to let in fresh air. Use fans in conjunction with air conditioning to circulate cool air effectively.

By implementing these tips, individuals can optimize their air conditioning usage, minimize energy consumption, and maintain a healthy indoor environment, which is our ultimate goal as a consulting company specializing in air quality services.

E-waste, refers to discarded electronic devices such as smartphones, computers, and appliances that have reached the end of their life cycle.
The global accumulation of e-waste has become a significant environmental concern. It is predicted that by 2030, the total amount of electronic waste will be double that of 2014.
Does the concept of a circular economy offer a promising solution?
The circular economy aims to minimize waste generation by promoting the reuse, repair, and recycling of products. In the context of e-waste, the circular economy encourages proper disposal methods and the extraction of valuable resources from discarded electronics.
To support the circular economy, the production of electronic products should prioritize the use of sustainable materials, incorporate modular and innovative design for easy repair… In this concept there are some interesting products….
