We do not know what kind of work environment we'll all be facing on the other side of the coronavirus, or when.
With many employees being sent home, others out of work and many more confused about what's ahead, it's never been more important to keep ourselves busy and prepare for an uncertain future.
One way is by upskilling. But with colleges and universities closing, how do you go about that? Welcome to MOOCs.
The world of Massive Open Online Courses is less than a decade old, but it has taken global learning by storm. If you've never heard of them, here's your starter for 10.
Most people of a certain age will remember the Open University on BBC2 when a beardy intellectual appeared on the telly at 2am to tell us about computing devices or engineering solutions.
Of course, these days, the OU has developed into a huge and very well-regarded institution, and certainly offers many online courses, along with 10 centres and over 250 tutors in Ireland alone.
While the undergraduate and masters degrees are well-known and cost a lot in fees, did you know they also run 700 free courses online under the OpenLearn Ireland portal?
How about intermediate French? Communications or financial markets? Forensic psychology? In fact, there's something to suit everyone.
Other courses are fee-based, but often at a fraction of what they would cost at a physical university. And if it's not a formal qualification you're after, then doing a cert, diploma or course simply for fun can cost nothing. 'The Digital Economy', for instance, takes 29 weeks, with four courses and an exam. It's free to study, but the certification will cost you €316. 'Business and Finance Fundamentals' takes 54 weeks, costing €512 with credentials.
You can learn a range of unlimited short courses (extramurals) by signing up for €239.99 for a year.
Many third-level institutions, aided by philanthropists and governments, also offer an enormous range of learning, from short snappy courses of interest to full-time degrees.
If you're at home, at a loose end, and would like to engage your brain and perhaps learn a new skill before going back into the workplace - without ever having to leave your house - then all you need is a computer, broadband and the will to learn.
While some courses inevitably require qualifications or an educational achievement, many do not, and are open to all. MOOCs are generally taught by online tutor-ial, video, collaboration with mentors and other students, and can be studied in your own time.
Filmed lectures, a reading list and exams often feature, and many students report the best bit can be the user forums where like-minded students 'meet' to discuss ideas.
Other benefits include access to global experts, online collaboration, different resources and wide-ranging topics which your local college may not offer.
The best websites, which offer hundreds of courses with dozens of universities worldwide, including Harvard, MIT, Berkeley, and our own Trinity College, DCU and UCD, are:
With 500 courses from more than a hundred universities, most of this MOOC's options are free of charge to study, but have a payment for accreditation or certificate. Examples include 'Accounting and Finance for IT Professionals' through the Indian Business School. Learn about balance sheets, cash flow and all things business over four weeks.
This vast space includes some of Europe's top universities.
At the University of Aberdeen, you can do 'Nutrition and Wellbeing' for four weeks (three hours per week); 'Innovation and Enterprise' at the University of Bristol (four weeks, three hours per week); 'Getting to Grips with GDPR' at University of Groningen, Holland (two weeks, three hours per week); or Leiden University's 'Demystifying Mindfulness' for six weeks (six hours/week) - all for free.
'How to Write Your First Song', for budding songwriters, is six weeks, three hours/week from the University of Sheffield.
'The Music of The Beatles' takes seven weeks (2-4 hours/week) at Rochester University, while 'Guitar for Beginners' (Berklee College of Music) takes six weeks (6-8 hours/wk). Or try your hand at 'Creative Writing' at Wesleyan University for four weeks. All free.
Courses are paid (with some free). 'Marketing Analytics' over three months will cost €477 p.m. 'Digital Marketing' is a three-month course (10 hours/week) costing €179 p.m. on a pay-as-you-go basis.
