Could AI replace stand-up comedians and scriptwriters? This may not be an impossible dream if you accept that nothing we do is forever beyond the scope of computer modelling.
International negotiations concerning our environment such as on climate and biodiversity, often put the scientific case behind economic and political interests, with potentially disastrous consequences. What does that mean for human prosperity and even survival?
Cyberwar is not waged on physical battlefields following rules of engagement. Aggressors worry less about collateral damage, in part because they aren’t forced to confront the sight of an enemy bleeding to death before their eyes.
Even the most humdrum of electrical devices nowadays contains at least one computer; yet surprisingly few people are aware of their history, their form or function. In this talk we will see that not only is the history of computers rich and diverse, their architecture likewise.
There is a seismic shift underway in economics, hastened by the aftermath of the Covid-19 pandemic. Communities and countries around the world are beginning to adopt/consider adopting well-being and prosperity as major guiding principles.
The baby boomers have accumulated assets and have generous occupational pensions. Should they pass these assets to their descendants, with the risk of growing inequality, or should they be taxed to benefit society as a whole? Is inheriting morally dangerous? Or are inheritance taxes theft?
Niklaus Wirth said Algorithms + Data Structures = Programs. But programs are more than that. They are ubiquitous in modern life, but only a tiny minority of the population know how to program.
Humans use computers to do gigantic calculations which would be impossible to do by hand – for example, weather prediction. But could an AI go beyond that and come up with a proof of a theorem which has stumped humankind?
Data structures are the critical ingredient of all good information systems. Poor data structures lead to horrendous problems of interoperability and nightmarish complexity; good ones can make the ‘uncomputable’ computable.
