The Way Things Have Always Been Done is almost inevitably wrong. Since Queen Victoria learned to write with a quill pen, there are new and better ways to communicate. (Including technology to type out what is dictated into the laptop)
There is no excuse for stubbornly sticking to anything else done the way it has been for centuries. Covid19 or not, there is no need to round up any group and force them into physical attendance in a building. (Australians were home schooling long ago, but it was work posted and work discussed by contact with teacher by radio)
The potential for new technology is transformative and inclusive, with enormous benefits. Cost, of course, since the State will not need to fund most of the buildings involved in any level of education. Inability for bullies to access victims. Ability of the previously excluded to be included e.g. those with physical difficulty can learn from their bed.
Also, there is no need for the segregation by birth date. If a parent notices an online class of interest, they will study. If a young child races ahead of anyone his own age, because he is entranced with an area of learning, nothing need hold him back. Individuals of all ages can find their level, and can devise their own personal syllabus.
Learning has long been in need of change, because it is obviously not possible to assume any knowledge (including professional) is 'done to you' in youth, (by sitting with a teacher/lecturer repeating what they and their grandfather were told) and then you have a way to earn a living for the rest of your life.
The most practical skills probably have the best staying power, so a care assistant or farm labourer or plumber may be more securely employed than a lawyer, whose body of knowledge may be overturned by an app. which does the job better, faster and nearly free of charge
If schools are regarded as childminders, there are better, cheaper ways to do that. More parents and more firms will insist on WFH, so merely having someone in the same building as the child is a much smaller problem now. Further education practical and sandwich courses have been wrongly despised and deprived of funding. Now, it must be obvious that permitting infantalised adults to spend full time years to study a single degree subject is virtually never sensible.
The home schoolers have pioneered, so did the O.U. But now everyone must exploit the range of new possibilities. Professional educators can check on pupils doing work devised by the finest experts in the world. U.K. is miles behind, educationally and in health standards clearly.
