Gemini’s free tier is crazy good. Built the same high-quality slide deck in seconds while ChatGPT blew through half my 5-hour limit.#ChatGPTvsGemini

Reaching your ChatGPT message limit not because you accomplished a lot, but because you had to restart 5 times to fix constant errors... peak frustration. 🙃#LimitReached

It was an honour to present at #PSIDevCon2026 and serve as a panellist at the 20th Public Sector Innovation Conference in Bela-Bela on 20 August 2026. A valuable platform to advance open-source, AI and digital innovation for better public services. #InnovationForImpact

The pace at which AI is improving is mind-boggling. Mainstream AI has evolved from an amusing piece of software that could do some coding into fully functional coding houses. What comes next?

[Karel Joubert @kareljj]

A privilege to serve as a panelist at the launch of the African Digital Transformation Centre at the Innovation Hub in Pretoria.
Exciting discussions on connectivity, digital skills, and the future of digital transformation across Africa.
Thank you @ITU & #DCDT #ICT #4IR

Anyone else having issues with ChatGPT timing out and not giving complete outputs? I wish they’d roll back to the previous version!

[Karel Joubert @kareljj]

I've had some experiences with the newly released Chat GPT5 that haven't met my expectations. I've encountered numerous programming errors, frequent timeouts, resulting in a rather disappointing and frustrating experience so far.

[Karel Joubert @kareljj]

Is it just me, or is AI getting dumber by the day? Are we heading toward glorified spellcheckers? ChatGPT, in particular, is becoming disappointing, at this rate, I'll soon spend more time checking its output than I save by using it

AI is rewriting the rules—jobs disappearing FAST, opportunities slipping away. Those who don’t wake up now will regret it SOON. Time to get AI-fluent—or get left behind. #AI #WakeUp

However it is not good enough to just be users of open source software, we must also become producers thereof.

[Karel Joubert @kareljj]

The time has come to look at Open Source as an alternative to proprietary software to save cost during the COVID-19 pandemic.
Software like Libre Office, Open Project and QGIS offer excellent replacements for their proprietary counterparts at zero the cost.
