While this is an impressive step forward, there remains an extremely long way, probably of several decades, until being able to design and synthesize a cell comparable in complexity with a bacterium.

The thing that they made is more alive than a crystal, which when placed in a suitable solution will grow and reproduce its own structure, but much less alive than even the simplest known living cells.

Its "life" is similar to that of a brain-dead human, whose body is not left to die by a bunch of machines that pump air into its lungs and nutrients through its blood vessels.

The techniques developed to make this pseudo-cell might evolve eventually into techniques able to make a true cell and it is likely that valuable information can be extracted from experiments with it, but it is very unlikely that any of the ancestors of the living beings has ever had even a remote resemblance with this (because it is far too dependent on continuously receiving complex cellular components and nutrients from outside; simplified parasitic living beings could appear only when there already existed sufficiently complex living hosts for the parasites).

Some components of this thing are growing by reproducing themselves, but like I have said, so does any crystal, thus it is difficult to choose a criterion that will distinguish with certainty what is living from what is non-living.

The growth is followed by a kind of division into 2 vesicles, but that happens by a mechanism very different from any living cell. Many inorganic things will split when growing over a certain size, so again it is hard to decide whether this can be called living.

A brain-dead human is alive, but just facing systemic collapse, aka death. That's not to imply that what the scientists here have created is alive, but the comparison isn't so apt.

As a multi-cellular organism, a brain-dead human is not alive, even if most of its cells may remain alive as long as they are fed from outside.

OK, what I have said above is not generally true, as some brain-dead humans may be more alive than others, e.g. some integrative functions, like some feedback loops that function through the endocrine system or through the autonomous nervous system, may still be working, connecting some organs with each other.

My comparison was with a very dead brain-dead human, who was reduced to the equivalent of a tissue culture.

These artificial cells also have some components that continue to work like in a living cell, doing some nucleic acid replication and some protein and lipid synthesis from precursors provided from outside, but they lack the capability to perform many of the chemical reactions that would be needed to close the complex network of feedback loops that enable a true living cell to live autonomously.
